Now I don't know if this is an issue because the fish are acting normal, and I tested my water yesterday, everything was where it usually is in my tanks. I noticed this after my fish recovered from their ich, I was treating ich, its went away, but I noticed weird white lumps on their heads, it's most obvious on the oldest orange platy, I haven't noticed it on my Cory catfish. The grey juvenile that has it is acting normal and healthy, but the orange adult is being very skittish. Also, I noted that the orange appeared to be pregnant since she suddenly gained weight when they got ich, but after the ich was gone her stumach size went back to normal, no fry in the tank, they didnt get eaten if they where because I always have a lot of survivers, especially now that my tank has plants in it. I don't know what to do but it is puzzling me where this white lump came from.
