The Dragon Goby is a popular fish species that is easy to maintain. They like to swim in floating plants, so the tank should be decorated with live or plastic plants.

This fish can also tolerate slower-moving water than many other freshwater tropical fishes, and it's not too shy about accepting food at the water's surface.

These small, meat-eating fish are found in slow-moving streams and ponds in Africa and Asia. They use their long, continuous dorsal fins to help them "walk" on the bottom of their habitats in search of food.

This article will provide you with all the information you need to know about the Dragon Goby so that you can care for it in its natural environment.

They are also known as the Violet Goby because of their unique coloration. It is also sometimes called the Dragon Fish or Dragon Eel. This freshwater fish is native to Africa and Asia and can be found in slow-moving streams and ponds. The Dragon Goby gets its name from its long, continuous dorsal fin, which gives it the appearance of a dragon.

The Dragon Goby is a brackish water fish that can tolerate fresh and saltwater. However, it is essential to note that the Dragon Goby is not a true eel, despite its common name. The Dragon Goby is a member of the goby family, including over 2,000 different species of fish.

Possibly because they require a fair amount of care, it is not a very common fish in the aquarium trade. However, those interested in keeping this unique fish as a pet will be rewarded with a beautiful, active addition to their tank.

Expect to pay between $10 – $15 for a Dragon Goby for your aquarium. It is always best to purchase your fish from a reputable dealer to ensure that you get a healthy, well-cared-for fish.

Dragon Goby Appearance

The Dragon Goby is a very unique-looking fish with its long, continuous dorsal fin. This fin extends from the back of the head all the way to the tail. The dorsal fin is what gives the Dragon Goby its common name, as it gives the fish the appearance of a dragon.

Dragon Goby Appearance

Their body is long and slender, with a small mouth with sharp teeth. The teeth are used for grasping and crushing prey. The Dragon Goby's eyes are large and protrude from the top of its head.

Its eyes are very small in relation to its body size, which is common among fish that live in murky waters. The Dragon Goby's eyes help it to see prey that might be hiding in the mud at the bottom of streams and ponds.

The Dragon Goby is typically a brown or olive color, with a lighter belly. However, some Dragon Gobies can also be violet in color. This is the reason why the Dragon Goby is sometimes called the Violet Goby.

Initially, you may not be able to differentiate between the fins and the fish's body. However, upon closer inspection, you will notice that the fins are actually clear and have a purple tint. Their scales are large and rough, giving the fish tough skin. The scales on the belly of the Dragon Goby are smaller than those on its back.

This fish also has two barbels, or whiskers, on each side of its mouth. These barbels are used to help the Dragon Goby find food in murky waters. The ventral fins are easily visible on the Dragon Goby, and they are located just behind the gills. These fins help the fish to swim and to keep itself upright in the water.

Male and female Dragon Gobies look almost identical, making it difficult to tell them apart. However, the males are usually slightly larger than the females.

Dragon Goby Size & Growth Rate

They can grow up to 24 inches in length, making them one of the larger freshwater fish. However, most Dragon Gobies that are kept as pets only grow to be about 12 inches long.

Dragon Goby Size & Growth Rate

This fish has a relatively fast growth rate and can reach its full size within a year or two.

However, their growth rate will depend on several factors, including diet, water quality, and tank size.

Dragon Goby Lifespan

The Dragon Goby has a lifespan of up to 10 years, although the average lifespan is closer to 5 years.

Like most fish, their lifespan will be significantly affected by their diet, water quality, and tank size.

Dragon Goby Behavior & Temperament

The Dragon Goby is a peaceful and easy-to-care for fish. They are a good choice for beginners and make a great addition to most community tanks.

Dragon Goby Behavior & Temperament

They are bottom-dwelling fish and will spend most of their time near the substrate. They prefer to live in groups and do best when kept in tanks with at least five other fish.

It looks extremely fierce, as it hails from the ocean's deep waters, but it is actually quite gentle. The Dragon Goby is an active fish that will swim around the tank for food. They are not known to be jumpers and are unlikely to jump out of your tank.

They are peaceful fish and will get along with most other fish. However, they may be bullied by larger or more aggressive fish.

They does not have a good vision, but they have a keen sense of smell. This helps them to find food and to avoid predators. They are not known to be a fin nipper and are unlikely to damage other fish's fins.

Dragon Goby Breeding

For breeding, first, you have to differentiate between a male and female Dragon Goby. The easiest way to do this is by their size, as females are usually much larger than males. Another method is by examining the first dorsal fin, on males, it will be longer and pointier, while in females, it will be shorter and rounder.

The next step is to set up a breeding tank; this should be at least 30 gallons filled with soft water. The tank should also have plenty of hiding places for the parents and fry(baby fish). It is also recommended to add some live plants to the tank as the fry will often hide amongst them.

Once you have your breeding tank set up, you can then add your chosen pair of dragon gobies. It is best to add the female first and then introduce the male a few days later.

Once the pair has been introduced, they will usually start mating within a week. The female will lay her eggs on a smooth surface such as a rock or piece of driftwood. After she has laid her eggs, the male will then fertilize them.

The eggs will hatch after 5-7 days, and the fry will be free-swimming a few days later. At this point, you can start feeding them small live foods such as brine shrimp or daphnia.

The fry will grow quickly and should be large enough to be moved to a grow-out tank within 2 months.

Now that you know how to breed dragon gobies, you can enjoy watching them raise their young in your own home.

Dragon Goby Care

Caring for your Dragon Goby is not as difficult as it might first appear. These fish are actually quite hardy and can tolerate a wide range of water conditions. However, there are still some things that you need to do to ensure that your Dragon Goby is healthy and happy.

Here are some tips for caring for your Dragon Goby:

Tank Size

Like most aquarium fish, the Dragon Goby needs a tank that is at least 30 gallons in size. However, because of their large size and active nature, it is best to keep them in 50 gallons or larger tanks.

If you are keeping more than one Dragon Goby, you will need an even larger tank. It is best to have at least 50 gallons for each fish.

The Dragon Goby is a bottom-dwelling fish, so you will need to provide it with plenty of hiding places. Driftwood, rocks, and caves are all good options. Be sure to leave plenty of open space for the fish to swim.

Water Parameters

Dragon Gobies are not particularly finicky when it comes to water conditions. They can tolerate a wide range of water parameters. However, it is still essential to maintain good water quality in your tank.

The ideal water temperature for Dragon Gobies is 72°-82°F. The pH level should be between 6.5 and 8.5, and the hardness should be between 10-20 dKH.

The water hardness is particularly important for Dragon Gobies. These fish come from waters that are very soft, so they are not used to high levels of hardness. If the water in your tank is too hard, it can cause health problems for your Dragon Goby.

To maintain good water quality, you will need to do a partial water change of 20-30% once a week. Be sure to use a good aquarium filter and vacuum the gravel to remove any waste.

If you are keeping more than one Dragon Goby, it is best to have a larger tank with a sand substrate. This will help keep the water clean and provide the fish with a place to burrow.

Filtration

Dragon Gobies are not particularly messy fish, but they do produce a fair amount of waste. For this reason, it is important to have a good filter in your tank. A good filter will help keep the water clean and remove any waste products from your Dragon Goby.

There are a variety of different filters on the market, so you will need to choose one that is appropriate for your tank size. A good rule of thumb is to select a filter that is rated twice the size of your tank. For example, if you have a 20-gallon tank, you should choose a filter that is rated for at least 50 gallons.

It is also a good idea to have more than one type of filter in your tank. This will provide your Dragon Goby with the best possible filtration and will help to keep the water cleaner for longer periods of time.

Some recommended filters for Dragon Gobies are:

  • Canister filters: These filters are large and powerful, making them ideal for larger tanks. They are also very efficient at removing waste from the water.
  • Power filters: These filters are smaller and less expensive than canister filters, making them a good option for smaller tanks. They are not as efficient as canister filters, but they will still do an excellent job of keeping the water clean.
  • Undergravel filters: These filters are hidden beneath the gravel at the bottom of your tank. They are very efficient at removing waste from the water, but they can be difficult to clean.

Be sure to clean your filter regularly, as dirty filters can lead to poor water quality and sick fish.

Heating

Dragon Gobies come from warm waters, so they will need a heater in their tank. The ideal water temperature for these fish is 78-82 degrees Fahrenheit.

You will need to choose a heater that is appropriate for the size of your tank. A good rule of thumb is to choose a heater that is rated for at least twice the size of your tank.

Some recommended heaters for Dragon Gobies are:

  • Submersible heaters: These heaters are placed in the tank and can be hidden from view. They are very efficient at heating the water and are less likely to break than other types of heaters.
  • Glass aquarium heaters: These heaters are placed on the outside of the tank. They are not as efficient as submersible heaters, but they are less expensive.

Be sure to monitor the water temperature carefully, as too much or too little heat can be harmful to your fish.

Plants

Dragon Gobies are not particularly finicky for plants, but they prefer live plants over fake plants. Live plants will help keep the water clean and provide your fish with a place to hide.

Some recommended plants for Dragon Gobies are:

  • Java fern: This plant is very easy to care for and can tolerate a wide range of water conditions. It is a good choice for beginners.
  • Java moss: This plant is also very easy to care for and can tolerate a wide range of water conditions. It is a good choice for beginners.
  • Anubias: This plant is a little more challenging to care for than the previous two, but it is still suitable for beginners.

Be sure to choose plants that are appropriate for the size of your tank. Larger tanks can accommodate more plants than smaller tanks.

Lighting

Dragon Gobies do not require special lighting but prefer dimmer lights. Fluorescent bulbs are a good choice for these fish.

Be sure to provide your plants with the appropriate amount of light. Too much light can cause algae to grow in your tank.

Some recommended lights for Dragon Gobies are:

  • Fluorescent bulbs: These bulbs come in a variety of sizes and shapes. They emit a soft, white light that is perfect for Dragon Gobies.
  • LED lights: These lights are more expensive than fluorescent bulbs, but they last longer and use less energy. They emit a bright, white light that can be too intense for some fish.

Be sure to experiment with different types of lighting to see what your fish prefer.

Gravel

Dragon Gobies are not particularly finicky when it comes to gravel, but they do prefer dark colors. Black or dark blue gravel is a good choice for these fish.

Be sure to choose gravel that is appropriate for the size of your tank. Larger tanks can accommodate more gravel than smaller tanks.
