I saw one in my tank the first week I set it up in 2006... Didn't see any again until earlier this year and now I have hundreds. They are just really good hiders. So where they came from is likely hard to say. Just watch them as a few species have a tendency to eat some corals...Where did they come from, I think I found another one? We haven't added anything to the tank in over a month. I suppose they could have always been here and I just never saw it before.
Thanks for identifying the little critter.
they can, but it takes a whole lot of them to feed the shrimp. if the tank is large enough and the algae is growing well enough then yes you can use Asterina's for food.Will harlequin shrimp eat those little starfish? Cause I too am tierd of buying the chocolate chip stars for mine. You must at mit it is fun to watch them tear into that starfish and drag it around the tank. lol
