Disappearing fish.

[daniella3d]

My guess is that your fish died and the crab ate it. Shrimp usualy die and decompose. I had 3 fire shrimp that died without much trace. 2 killed eath other and soon after died. One was missing all of its legs from the battle. The other remaining lived for another 6 months and died, then was eaten by the little crabs in my tank. Small fish especialy can be consumed fast.

I think a mantis would need to eat quite a bit more than 2 fishes in a 1.5 year. You already know the clown died, the rest probably did the same. Most fish tend to hide when they are sick and probably die when hiding.

So far have lost a firefish blenny, a lawnmower blenny, and one clown (he just died though... about 3 yrs old.... poor guy). The other two I never saw again. Shrimp don't seem to last long either.

I know the usual suspect is a Mantis.... but I have never seen one, never heard one, have put out traps... and nothing.
I do have some biggish emerald crabs.... could they do it? Rawr. I miss my fish!
