I'm unsure cause one one hand I don't want it to spread and on another I don't really mind those bumps if that's all that happens if they get infected. But I don't want to just buy some treatment and not even sure if it will stress him out or heal the fish. ALSO, the 4 in my tank get really scared at night and 1 has jumped onto the glass(he went unresponsive and I had to manually remove him, he never tried to free himself.) I believe he is stressed about smaller school? But what if those fish get sick? I'm kinda stuck
