Will a yuma split? I've got one doing something right now. It has slime covering a portion of it, the mouth is off-center. The color looks just like it always has, and all the other yuma's in the tank look "happy" as well. I've read that if they are unhappy they will usually detach from the rock they are on, or cover themselves in a brown colored slime. Is that true? The slime coming out of this one is white. Anyone have any insight?
