These guys were in a little tank together and are clearly not happy. Is this a fungus? I've sprayed them with some fungicide and the new leaves haven't spotched over yet.
None of my bicalcs look good even though they're pitchering. Only the one in the photo was in the tank with the rafflesiana in the photo-the others weren't doing well in another tank.
I admit that air circulation is a problem that I'm trying to address but the humidity levels are at least 75% and the temps are probably in the 70s or 80s.
