Where did my fish GO?

[dockmasterjc]

It first started last year with a pseudochromis, then a few months ago 2 chromis within a couple weeks. Now my hippo tang is nowhere to be found. They did not jump, I couldn't find any evidence of scales or pieces of the departed. I think it has to be my brittle star. Any thought are greatly appreciated. The other fish I have in there are 2 clowns, a mandarin, one chromis and an algae blenny.

Look carefully in your overflow, and behind/under your tank. Seems like a lot for a brittle to eat.....

How big is the brittle star? From what I have heard, as they get larger, they go after bigger and better pray. But alas, I could be wrong.
