Double Sea Star (Icon Sea Star)
The Double Sea Star, also known as the Icon Sea Star, originates from the reefs of the Indo-Pacific. The color of this star is orange to tan and exhibits very distinctive color patterns. The body of this star has many small circles, and is outlined with the pattern that follows into the legs. This outline creates another star shape, which gives rise to its common name, Double Sea Star.
It is found over sandy substrates, on rocks, and in crevices in the deeper parts of the reef. It is constantly foraging for micro-organisms and detritus to eat, so the aquarium should have ample amounts of live rock. It generally lives alone, but if the aquarium is large enough to support more than one, it will tolerate others of its own species.
The Double Sea Star is very intolerant of sudden changes in water conditions. Stable water parameters are essential for its health and survival.

FAQ
What are the ideal water conditions for the Double Sea Star?
The Double Sea Star requires stable water conditions. Sudden changes in temperature, salinity, or pH are not tolerated. Maintain consistent water parameters with regular testing and proper filtration.
Can multiple Double Sea Stars coexist in the same tank?
Yes, but only if the tank is large enough to provide adequate space. They generally live alone, and overcrowding may lead to stress or aggression.
What should I provide in the tank to support its diet?
Include ample live rock and sandy substrate to support foraging. The Double Sea Star feeds on micro-organisms and detritus naturally found in these environments.

Emma Gray –
The Double Sea Star is a striking addition to my reef tank. Its unique pattern and behavior stand out. I’ve kept it for six months and it’s thriving with no issues. The tank has plenty of live rock and sand, which supports its feeding habits. It’s calm and doesn’t interfere with other inhabitants.
Andrea Simpson –
Beautiful creature with a distinctive appearance. I noticed it foraging on the sand daily. The tank needs stable water conditions, which I’ve maintained carefully. It’s a peaceful species and fits well in a mature reef setup.
Julia Newman –
It arrived healthy and looks good in the tank. I’m still adjusting to its feeding habits. It seems to prefer areas with more detritus. I’ll monitor water parameters closely to avoid any sudden changes.
