I removed Rummlers door to see if he would come out last night, as I haven't seen him physically in about 2 weeks. I know the food in the tank has been disapearing except for one rather large crab. This morning I noticed he has a whit spot :( about the size of a 1/4 of a dime towards the top of one leg. My thoughts are maybe that the one crab that is remaining injured him. Inklet is happily dining on that crab now. Anyway, what do you think? I'm going to check my water parameters later after work. He is actively trying to reestablish his door but hasn't figured out his prior door is on the floor of the tank yet. Other that the spot, he looks healthy and fat.
