My cleaner shrimp are gone.

BTA, Giant Brittle Star, Strawberry Crab, Emerald Crab

I'm leaning towards:
Giant Brittle Star, In the Tank, With its mouth


Thoughts????? Two of them in two days are gone!

I checked the overflow and the sump/fuge......went through all the rock with a flash light, nothing. I've kept BTA and shrimp in the past with no problems.

Got two more coming tomorrow, need to put the murder in the sump asap!!!! :angry
