Aquarists with saltwater tanks actively seek out the Common Sand Sifting Starfish for several reasons. First and foremost, these starfish are voracious eaters of nuisance algae. They will help maintain your tank in tip-top condition without you having to do much work. They are also peaceful and make good tankmates for other similar-sized fish and invertebrates.
The name "Sand Sifting Starfish" is relatively self-explanatory. These starfish spend most of their time sifting through the sand, searching for food. They are equipped with tube feet that help them move through the sand and two long, slender arms that they use to scavenge for food.
The one drawback of these merry maids is that they sometimes eat small invertebrates, like shrimp and crabs. If you have smaller tank mates, you may want to consider another type of starfish.
The cost of a Sand Sifting Starfish will vary depending on the specimen's size, color, and age. Juvenile starfish are usually less expensive than adults. Prices range from $15 to $30.
Sand Sifter Starfish Appearance
The Sand Sifter Starfish is a beautiful creature with a broad, disk-shaped body. They have long, slender arms that they use to scavenge for food. The tips of their arms are often fringed with small, white bumps.
These starfish come in various colors, including orange, brown, yellow, and red. The most common color is orange.
The underside of the Sand Sifter Starfish is white or cream-colored. This helps them blend in with the light-colored sand on the bottom of the ocean. They have a small, central mouth located on the underside of their body. They also have hundreds of tiny eyes that are scattered across their arms.
They do not have a brain. Instead, they have a simple nervous system that runs the length of their body. This nervous system is responsible for its essential functions, such as moving and eating. So, don't be surprised if you see your starfish moving in a jerky, uncoordinated manner!
Males and females are complicated to tell apart. The best way to sex these starfish is to look for the gonopores located on the underside of their bodies. Males have two tiny pores, while females have one large pore.
Sand Sifter starfish Size & Growth Rate
The Sand Sifter Starfish can get up to 10 inches in the wild, but they are typically much smaller in captivity. Their size will also depend on the size of their tank. These starfish grow relatively slowly.
However, it is not uncommon for them to double in size within the first year of life.
Sand Sifter starfish Lifespan
The lifespan of a Sand Sifter Starfish is typically 3 to 5 years, but they have been known to live up to 10 years in captivity.
As long as they are well cared for, these starfish can provide years of enjoyment for you and your family.
Sand Sifter starfish Behavior & Temperament
When it comes to their behavior, Sand Sifting Starfish are peaceful and easy habitants to keep in a home aquarium.
They are not known to bother other fish or invertebrates in the tank. However, they may eat smaller fish and invertebrates, so it is essential to choose tankmates carefully.
These fish are also very active and will often be seen sifting through the substrate in search of food.
Sand Sifting Starfish Breeding
Sand Sifter Starfish are not known to breed in captivity. If you are interested in breeding these fish, you will need to collect a male and female from the wild. Once you have collected your fish, you will need to set up a breeding tank.
The breeding tank should have:
- A sandy bottom
- A well-established live rock
- A water temperature of 72°-78°F
- A salinity of 1.020-1.025
- A pH of 8.1-8.4
Once you have set up your breeding tank, you will need to acclimate your fish to the new environment. You will need to slowly add water from the breeding tank to the fish's current tank.
Once the fish have acclimated to the new environment, you will need to provide them with various foods. The female fish will lay eggs on the live rock, and the male fish will fertilize them. Once the eggs have hatched, the fry will need to be fed a diet of live foods.
Sand Sifting Starfish Care
Sand Sifting Starfish are relatively easy to care for, but there are a few things you need to know before adding one to your tank.
The first thing you need to do is choose the right size tank. These starfish can grow up to 10 inches, so they need plenty of room to move around.
The next thing you need to do is choose the right type of substrate. These starfish spend most of their time sifting through the sand, so you need to make sure you have fine sand enough for them to move through quickly.
You also need to provide plenty of hiding places for your starfish. Live rock and coral are great options. These starfish like to hide under rocks and in crevices when they are not out looking for food.
The last thing you need to do is choose the right type of food. These starfish are scavengers, so they eat just about anything you put in the tank. However, they do need a diet rich in calcium and other minerals.
Here are some tips for keeping a Sand Sifter Starfish:
The Sand Sifter Starfish needs a minimum tank size of 10 gallons. They are active creatures that need plenty of room to move around, so a larger tank is always better. However, these starfish can do well in a nano tank as long as they have enough sand to sift through.
When setting up your tank, make sure you use fine sand. This will allow your starfish to move through the substrate easily and help prevent them from getting injured.
The Sand Sifter Starfish is a saltwater creature, so you need to ensure your tank is cycled adequately before adding one.
