went to florida for the last few days and when I got back yesterday I noticed I had lost a clownfish . . . the male was swimming around but the female was nowhere to be seen. Ive checked the overflow, the rocks, a 5 ft radius around the tank, the CL, the sump . . . its like shes just disappeared! I do have crabs in there, so there is a possibility that she got taken care of already but there is no ammonia traces . . . any other ideas?
