Frogspawn Coral, scientifically known as Euphyllia divisa, is a hardy and beautiful species of stony coral. They are also called Frogspawn Leather Coral, are bryozoans - filter-feeding colonial animals that live on the substrate.

They bear a close similarity to corals, which is why they are commonly mistaken for them and given names such as "Button Coral."Frogspawn corals are members of the "Anthozoa" family, which means that they are closely related to other types of coral, such as sea anemones.

However, frogspawn corals are considerably more difficult to keep in captivity because they have a very high metabolism and require a lot of food.

Frogspawn corals get their common name from the fact that they look like a bunch of small, pink eggs. These corals are usually found in coral reefs and can grow to be quite large. They get their nutrients from photosynthesis, but they also require a lot of food to stay healthy.

Frogspawn coral is a great beginner coral because it is so easy to care for and should have almost no initial cycling period before you can start enjoying the beauty of your first colony.

Frogspawn corals are bright green with black polyps that will look similar to frog spawn. They should be placed in a well-lit area but out of the way of higher intensity lighting such as Metal Halides. It requires low to moderate light and turbulent water flow.

There are about 100 kinds of Euphyllia corals that can be kept in captivity. The Frogspawn Coral belongs to the large-polyp stony (LPS) family, and it is a common and popular coral among reef hobbyists.

Frogspawn corals are considered one of the "Tough" corals, meaning they may not be ideal for beginners unless kept under perfect conditions. An experienced reef keeper could easily maintain this coral and enjoy its beauty for years and pass it on to someone else.

The Frogspawn Coral is azooxanthellate, meaning it contains photosynthetic algae (zooxanthellae) in its tissues. This gives the coral its characteristic green color.

The algae provide the coral with most of its food and oxygen through photosynthesis. In return, the coral provides the algae with a safe place to live. If the algae are lost, the coral will lose its color and will likely die.

Frogspawn Coral can be kept in reef tanks with other LPS corals as well as soft corals and anemones. It is generally not recommended to keep them with fish because they may eat the coral. In a well-maintained fish tank, Frogspawn Coral can grow to be quite large.

They are not aggressive towards other corals or sessile invertebrates, but they can damage themselves with their sweeper tentacles.

When the coral gets stressed, it will release its sweeper tentacles to start over. It is best to provide enough space between your corals so they do not touch each other.

Frogspawn Coral can be propagated by cuttings. The coral will form a small colony on the new piece of rock, and the keeper can then break it off and place it in a tank with lower lighting. Frogspawn Coral generally lives for several years if provided with good water conditions and lighting.

Facts And Characteristics Of Frogspawn Coral

Some of the facts and characteristics about Frogspawn Coral are as follows.

How Do Frogspawn Coral Look Like?

Frogspawn Coral is one of the nicer-looking corals that you can add to your reef tank. The coral looks similar to frog spawn due to its green texture and black tips. You should take a look at this coral if you want something different than the typical brown color of many other corals.

Frogspawn Coral

They have a hard exterior and an oval-shaped base with cone-shaped tips as well as small holes throughout the surface.

They have a high density of polyps, which is why they can come in many different colors, including green, yellow, brown, or purple. The surface of the coral is often smooth, but it can also have a bumpy texture.

The polyps are retractable and will extend during the day to feed. Their color and shape can vary, and they may be black, brown, orange, or green. The polyps will also retract during the night to protect themselves from predators.

Frogspawn Coral generally grows in grouping and looks like a large cluster of pinkish-green rocks surrounding a central mound. With time, small branches grow out from the original colony's base.

They grow with small bumps that are arranged in rows, forming a rough surface. The tips of the branches have black polyps that look similar to frog spawn.

Their appearance can change depending on their location and the water conditions. If they are in a well-lit area with a high water flow, they will be green with black polyps. If they are in a shaded area or low-light areas, they will be brown or yellow.

The appearance of the frogspawn coral may change if there is a problem with the lighting or its food source. If your frogspawn does not look like it used to, there may be a problem with the lighting. It is easy to tell if this is the case because they tend to get lighter in color when they are not receiving enough light.

If your frogspawn coral has turned green, it could have algae growing on its skeleton, which will prevent it from getting light. You need to get rid of the algae if you want the coral to return to its original color.

Frogspawn coral gets their food from the water and photosynthesis. If there is not enough light, they will not be able to photosynthesize and will rely on the water for food. This can cause them to lose their color and turn green.

When compared to other corals, they are not very ornate, but they are a nice addition to any tank.

Average Size And Growth Of Frogspawn Corals

Frogspawn corals can grow to be quite large in a reef tank. They can reach a size of up to 12 inches across, so make sure you have enough room for them.

Frogspawn Coral

In the wild, they can be even larger and can grow up to 18 inches across. Their size will depend upon the space they have to grow, the water conditions, and the lighting.

They weigh up to 30 pounds and can be kept in tanks that measure 100 gallons or more. If you keep them in a sump, the sump should not be smaller than 50 gallons.

When born, frogspawn coral polyps are very small, around 1/8 inch in diameter. They will grow to their full size over time. They are not as small as some of the other corals and will need at least a 6-inch space between them and other corals. They can be placed in the center or sides of a tank.

Habitat

They are commonly found in reefs and protected lagoons in the Indo-Pacific region. They can be found singly or in colonies and prefer water that has a temperature of 74-78 degrees Fahrenheit (23-25 degrees Celsius).

Frogspawn Coral

They can also be found growing on rocks and coral reefs. They live in areas with lots of nutrients and planktonic food.

Geographically, they are found in many areas of the world, including Texas, Florida, Bermuda, Australia, Japan, Taiwan, China, Philippines, Indonesia, and Polynesia. They prefer a location with plenty of sunlight and warm water.

They are usually found in crevices or caves on reefs with little water movement, but not too much. They prefer areas where there is lots of plankton to eat, which they catch using their tentacles.

They are located in a lot of areas across the world but do not live in extremely deep waters. In the wild, they tend to be located from 1-109 feet (33-33 meters) below sea level.

They are native to some parts of America, Africa, Europe, India, Australia, China, Japan, and South America. They can be found in many different types of habitats, including salt marshes and estuaries.

During the day, they are usually found partially buried in the sand, while at night, they emerge to feed. In addition to this, they are also found in areas that have strong ocean currents.

Breeding Of Frogspawn Corals

Frogspawn is hermaphrodite, meaning they have both male and female reproductive organs. When two frogspawn is placed close together, they will fertilize each other, and the eggs will be released a few days later. The eggs will be pink or green and will be attached to the coral's skeleton.

Frogspawn Coral

The eggs will hatch in about two weeks, and the larvae will then attach themselves to a hard surface. They have a velum that they use for swimming, and they can float around the tank looking for a place to settle down.

Frogspawn does not release eggs and sperm at the same time, which is another feature that makes it different from other corals.

This type of coral is also a broodstock, meaning the larvae will stay in one spot and not move around. They will stay there until they are ready to metamorphose into an adult.

Frogspawn Coral in the wild is almost impossible because they release their eggs and sperm into the water to reproduce.

They are one of the few corals that do not reproduce through fragmentation. On the other hand, they reproduce very well in captivity because it is easy to grow them in an artificial environment.

In aquariums, frogspawn coral can be propagated by cutting certain parts of the mother colony off and placing them on another rock. Since Frogspawn Coral is a slow-growing coral, it can be difficult to tell when they are sexually mature.

They will only release their eggs and sperm when they are mature, which is usually after a few years of growth.

Temperament Of Frogspawn Corals

The behavior of these corals can vary depending on their environment. In captivity, they can be very aggressive and will sting other corals. This can be a problem if they are in a tank with other types of corals.

Frogspawn Coral

In the wild, they are usually found in colonies and will not sting other corals. They are also known to be one of the first corals to appear in an area where they are found. In tanks, they can be kept singly or in small colonies. Also, if they are kept in a tank with other corals, they will usually be the last to sting.

They will usually retract their tentacles when they are stressed. If the water is too hot, they will lose their color and turn green. They can also lose their color if there is not enough light.

The frogspawn coral walks around the tank using its tentacles, which are called tube feet. It moves by attaching itself to the substrate and pulling itself along with its many tube feet.

After it settles down, it will start to grow by getting bigger and developing new polyps. The only way it can move is by crawling.

In colonies, they will release their eggs or sperm into the water to reproduce. This is also how they can spread out to different areas in the wild. They will only be able to move by attaching themselves to other colonies of frogspawn coral because they are too heavy to float around like other corals.

Behaviorally, they are usually peaceful but can be aggressive when they are in captivity. They will usually only sting other corals if they are near them. They can also lose their color if they are stressed.

Social Structure

Coral lives in colonies, which are groups of the same animal. They are usually found in large colonies that hold several different types of coral, including other frogspawn corals. This is because it is easier to catch plankton when there are more polyps.

Frogspawn Coral

They live together for their entire lives, but each colony has one dominant male and female. The male and female release their sperm and eggs into the water to reproduce. They will only reproduce if they are in a colony because it is too difficult for them to move around and find another colony.

They live together because they feed on plankton and other small organisms, which can be found more easily in colonies than when they are alone. Having many polyps also helps split up the light so that it reaches more corals.

They like to live in colonies because it is easier to catch food. When they are in a colony, they can use their tentacles to grab the planktonic food from the water.

In captivity, they can live alone or in a colony. If it is put into a new tank with other corals, the frogspawn coral tends to be aggressive and sting other species of coral.

It is best to introduce it last after all the other corals have been introduced into the tank. This way, it does not harm them and is less likely to be harmed.

Frogspawn Coral Care Guide

The frogspawn coral is pretty simple to care for, as it does not necessarily need any special equipment. They are very hardy and may seem intimidating at first, but if you keep these easy tips in mind, they are slightly easier to care for than others corals.

Tank Requirements

The tank size must be at least 30 gallons to keep frogspawn coral in your tank. They can get quite large and need plenty of space to grow. It is necessary to have a tank this size so that they can grow and stay healthy.

Frogspawn Coral

It is important to cover the floor of the aquarium with 1-2 inches of sand or gravel. The frogspawn coral may try to dig itself down under the substrate. If it is unable to do so, it can cause stress or even death for the coral.

There must be enough sand or gravel to allow for this, or else there is a risk that the frogspawn may perish. They require a filter with a moderate current and plenty of oxygen. The frogspawn coral should be placed in an area of the tank where it will receive plenty of light.

They can tolerate a wide range of lighting conditions but prefer bright light. They do not require any special equipment to filter the water in their environment, but they do benefit from a moderate current in their tank.

A small powerhead is adequate for providing water flow in the tank and will also provide some filtration. For best results, they should be placed in an area where there are naturally high levels of oxygen.

The tank should be made to mimic their natural habitat as closely as possible. This means having areas with high and low light, moderate current, and plenty of places to hide.

Water parameters

Frogspawn corals can tolerate a wide range of water parameters but prefer water that is slightly alkaline and has a pH of 8.0-8.4. The water temperature should be maintained at 72-78 degrees Fahrenheit (22-25 degrees Celsius).

They do not have a strict water parameter, but they do not like to be in water that is too salty or has high levels of nitrates and phosphates. It is important to test the water parameters regularly and make adjustments as necessary.

They prefer strong lighting conditions because it helps them capture their food. They require at least 4 hours of moderate to strong lighting each day.

It is important to make sure that they are placed in an area where they will receive ample water flow but not turbulent currents because this could be very harmful to the frogspawn coral.

For best results, it should be placed in an area where it can receive both moderate currents and high lighting conditions. They have a wide range of water parameters that they can survive in, but the temperature should always remain between 72-78 degrees Fahrenheit (22 to 25 degrees Celsius).

Higher or lower temperatures should be avoided because it could cause stress for the coral and even kill it.

Lighting

The frogspawn coral requires at least 4 hours of moderate to strong lighting each day. They prefer brighter light conditions, so they should be placed in an area where they are receiving between 50-100 PAR. If the lighting is too dim, it will not have enough energy to sustain itself and may die.

Frogspawn Coral

Lighting is very important for the frogspawn coral because it helps them to capture their food. They use their tentacles to reach out and catch prey that is swimming nearby.

It is important to place them in an area where they will receive a lot of light, but not in an area where the water is too turbulent because this could be harmful to the coral. For best results, they should be placed in an area where they can also receive moderate currents.

It is not necessary to have any specific lighting equipment in the tank. These corals do not benefit from a special type of light or a special filter that assists with water flow or filtration. If there is strong lighting naturally occurring in the aquarium, then that is sufficient for the frogspawn coral.

Feeding

Frogspawn corals are easy to feed in captivity because they will eat a variety of meaty foods and fish food flakes. They have a strong feeding response, so it's important to keep them well fed. If their tentacles do not have enough food available, this can stress the coral and cause it to die.

Frogspawn Coral

They can be fed brine shrimp, Mysis shrimp, krill, clams, mussels, fish food flakes, or any other meaty food that is available in the area. They get their major nutrition from the zooxanthellae in their tissues.

It is important to feed this coral a variety of different foods because if there is not enough of one type of food available, it will cause stress for the frogspawn coral and can even kill it.

If possible, feed live foods as well as prepared foods to ensure that they receive a balanced diet. The corals should be fed at least 3 times a week or more if there is enough food available.

Frogspawn corals usually do not require any special equipment to help them feed. They will catch their prey by reaching out with their tentacles. However, if there is not enough food available in the tank, then it may be necessary to supplement their diet with some type of food supplement.

Frogspawn coral gets their food from the water and photosynthesis. If there is not enough light, they will not be able to photosynthesize and will rely on the water for food. This can cause them to lose their color and turn green.

They also eat zooplankton, which are small animals that float in the water. The polyp catches them by having a tentacle-like structure come out of its body to catch the prey.

Algae is also a source of food for Frogspawn Coral, but If there are too many algae in the tank, they may not get enough light to survive or be able to reproduce. When kept in captivity, the best food for frogspawn coral is Cyclopeeze, fish eggs, or brine shrimp.

Meaty frozen food can be fed to them once or twice a week. They will also eat flake food, but it should only be fed to them every other day to avoid overfeeding. In addition to this, they should also be given a phytoplankton supplement two to three times a week.

If you have frogspawn coral in your tank, it is a good idea to have a protein skimmer. This will help remove any excess food that the coral does not eat. It will also help keep the water clean and clear.

Propagation Of Frogspawn Corals

The frogspawn coral can be propagated by breaking off a small piece of the coral and replanting it in another part of the tank. It is important to make sure that there is plenty of sand or gravel on the floor so that it can bury itself. If it is unable to do so, it will cause the coral stress or even kill it.

Frogspawn coral can also be propagated by separating the coral into fragments. This can be done by using a sharp knife or razor blade to cut the coral into small pieces. It is important to make sure that each piece has a small amount of live flesh on it so that it can survive.

The frogspawn coral can also be propagated by using a method called "mariculture." This involves placing the coral in a small container with a small amount of water and then feeding it regularly.

The frogspawn coral can be propagated in a variety of different ways, but the most common way is by breaking off a small piece and replanting it in another part of the tank.

Common Diseases And Their Treatments

The main problem with keeping frogspawn corals is that they can catch diseases more easily than a lot of different types of coral. Common problems include white band disease, skeletal eroding band disease, and white plague disease.

Frogspawn Coral

The most common diseases include skeletal eroding band disease. This is caused by bacteria, which eat away at the surface of the coral. It can be treated in aquariums with antibiotics and copper compounds to kill the pathogen.

White band disease also affects frogspawn corals in captivity, but it can be hard to diagnose because it's so common for corals to lose some of their colors when they are stressed. The white band disease can also be treated using antibiotics and copper compounds to kill the pathogen.

White plague is the most common coral disease in captive conditions. It is caused by a parasitic dinoflagellate that attaches itself to the polyps and causes them to die off. It is usually treated with antibiotics or copper compounds.

List Of Other Possible Diseases With Cures

  • Bacterial infection – antibiotics
  • Parasitic infections – copper medication
  • Fungal infections – Malachite green dip

The most common problems that frogspawn corals experience in captivity are bacterial and parasitic infections.

Most of the common diseases that affect frogspawn corals are treatable, but it is important to act quickly when treating them because many of these organisms can be fatal.

It is also important for this coral to be kept in a well-stocked aquarium so they do not have to fight off infections as easily. It is important to keep the frogspawn coral at a high enough level within the tank because it may not be able to survive at a low level.

It is also important to keep the frogspawn coral away from other corals that may be more susceptible to catching diseases or that can cause harm to the frogspawn coral.

Frogspawn Coral Placement

The frogspawn coral prefers to be placed on a flat surface so that it can lay out and extend its polyps.

The frogspawn coral needs to have more than one place to attach itself because it may not all grow at the same rate, which could lead to pieces of the coral falling off and preventing new growth from occurring.

The frogspawn coral can also be attached to live rock, but it is important to make sure that the live rock is not too tall because the frogspawn coral may not be able to reach the top.

It is also important to make sure that there are plenty of places for the frogspawn coral to attach itself so that it does not fall off.

Conclusion

The frogspawn coral is a beautiful and interesting coral that can be propagated in a variety of different ways. This coral can experience a variety of problems in captivity, but most of them are treatable.

It is important to keep the frogspawn coral at a high level within the tank and to keep it away from other corals that may be more susceptible to catching diseases. It is also important for this coral to be kept in a well-stocked aquarium so it does not have to fight off infections as easily.

The frogspawn coral is an interesting type of coral that can make a great addition to any aquascape or reef tank. This species of coral has many different colors and can be easily propagated.

It is important to make sure that the frogspawn coral is kept at a high level within the tank and that it is not placed near other corals that may be more susceptible to catching diseases.

It is also important for this coral to be kept in a well-stocked aquarium so it does not have to fight off infections as easily. Thanks for reading!
