"-The incredible shrinking Linckia-
I have a blue Linckia that is orange in color. <Isn't that an oxymoron?

> I have had it for over six months. She moves around actively has no sores of any sort. The problem is that she keeps getting smaller and smaller, I feel that she may be starving what can I do, I don't want to lose her? <Unfortunately, this is all too common with Linckia stars, especially larger ones. Since their diet consists of mainly microfauna, it takes a pretty large and well established tank to keep them truckin'. You can hand feed them by placing bits of seafood (got any sponge based marine angel food?) on the substrate in front of it's path or literally drop it right on top. Try this a few times per week or more. Good luck! -Kevin>"
