I'm totally saddened by the passing of my little jaguar....Even though it was almost always in hiding, I still loved knowing it was there. Found it floating at the top of my tank with white markings (almost like a gooey substance) all over him. I'm not quite sure what it is, but it certainly killed the jaguar. Is it possible that my rubber nose pleco latched on to the catfish and this is a result of having it's slime coat sucked off? Or does this look like an infection of some kind? All other fish look fine.
