Okay, so I'm on number 3 now. I first noticed a dead hermit crab (sans shell) at about week 2. I thought one of my 3 CUC hermits had died. Low and behold, I see all three crawling around the next day. Noticed dead hermit number 2 about 3 weeks ago. Strangely enough... I still counted 3 hermits the next week. Here we are at week 8 and I pull another dead hermit out of the tank. Can you guess how many hermits I count today? 3.
So obviously, these must have been hitchhikers. Is there a kind of crab/filter feeder about the same size as a red legged hermit crab that resembles their dead bodies almost exactly, or am I in posession of a magic hat of a biocube?

So confused.
