Hi I have a black ghost knife fish his name is Wilbur. Anyway I got him a few days ago along with my 2 angels, and I'm noticing he's not really eating unless I put the food at his face. He doesn't move much and appears to be very very weak, and sometimes just sits there not moving till you poke him or something to start him up again. I try and keep him hidden in his little bell decoration cave thing so none of the other fish bother him much, another thing Ive notices are these strange white blotches on his sides. I am treating the tank with jungle parasite treatment for internal parasites for one of my angels and a danio which appeared to have an internal worm. I'm not sure if these are just his symptoms of this or something else. (And yes ofcourse I half dosed my tank I have scaleless fish.) Can anyone help me diagnose wilbur?
