Well I'm still undecided on returning my green brittle star... I hand fed it tonight and it was so cool! I had some shrimp with dinner so and I had set some (raw) aside for my land hermit crabs and decided to try to feed a bit to the star. He LOVED it! I've never hand fed a fish tonight and it was really so awesome (probably more so than it should have been)! The fish loved it too, it was a nice treat all around. I am kindof hoping that if I can keep the star well fed he won't bother my fish... kinda risky I know...
