I have lost a cleaner shrimp-- an emerald crab---a lawnmower blenny---and a fire shrimp als withing 2 weeks of putting them in the tank--the cleaner was in there the longest he was there for at least 6 months but didn't stay at the bottom of the tank he hung around the top---- no evidence after there dissappearance--no body pieces to speak of at all--i have a completly sealed bio cube tank too btw--- a slignt nitrate spike after they dissappear but not much at all--could i have a mantis eating his way thru my bottom feeder fish--oh and i have a huge rock on the bottom of my tank and it has a cave in it--i will fill in the cave and it reappears in a few days..any thoughts????
