We just started our 110 gallon fish tank not that long ago. We have six baby (almost 2 inch) cichlids of the more docile species. We bought an almost 2 inch striped Raphael catfish on Tuesday. We saw him checking things out in the tank and then he went into hiding that night after about 40 minutes in the tank. We couldn't find him. The next morning we turned over all the caves in the tank and still could not find him. Last night my husband raked the sand and no movement. When it was dark, I tried to feed him a little bottom feeder food to see if he would come out and nothing. We still have no idea where this fish is. My husband is convinced he is dead, buried in the sand. He actually wants to take out all of our decorations and move all the sand to find the fish. Is this common? How on earth do we get this thing to come out of where ever he is? And yes, we did check the floor and he didn't jump out.
