I have a 7 or 8 inch sleeper goby (freshwater) and he seems as healthy as can be! He swims around normal, eats, recognizes me and you know the rest. But i have been noticing he has some things on him. One being these white stringy things and kind of a red bump on his lips. He also has a couple of bumps on his scales and in those areas the scales are raised more than the others and they have a kinda pink tone to them. There is a fox face pimelodid and a rapheal cat in there. Could this be from him hitting their spikes or is it a disease of some sort? I will provide pics.
