What kind of starfish is that? I may be interested but need to know what the critters needs are! Thanks!
It is a Fromia sp. starfish, they come in as a "pink tile star". A bit less common in the hobby than the red varieties. They need careful acclimation and an established reef aquarium to do well long term. They feed on very small bits of organic matter around the tank (algae and bacterial films on rock and glass).
