Care
Echinaster callosus is a hardy species that can adapt to a range of aquarium conditions. It requires a well-established tank with plenty of live rock and a sandy substrate to scavenge for food. This starfish is an omnivore and will feed on detritus, small invertebrates, and organic films on rocks and glass. It's important to ensure that the tank is free of copper-based medications, as these can be lethal to starfish.
Reproduction
In the wild, Echinaster callosus reproduces by releasing gametes into the water column, a process known as broadcast spawning. In the aquarium, reproduction is less common but can occur if the environment is stable and the starfish are well-fed.
Habitat
Echinaster callosus is found in the Western Atlantic, from North Carolina to Brazil, including the Gulf of Mexico and the Caribbean Sea. It typically inhabits coral reefs, seagrass beds, and rocky substrates, usually at depths ranging from shallow waters to about 30 meters deep.
