Hi just need to ask I have a Red Eye Tetra and it has a white lump on it's side.All up I have five Red Eye Tetras and they all seem in excellent health including this one and swim around fast and seem happy.But this particular one has had this lump on his side for a little while and I guess it looks a little like a pimple only a bit bigger and white in colour.He eats really good and swims around fast and seems as if nothing is wrong.Sorry I can't provide a photo but was just wondering if anyone had any ideas what it is?
that sounds like "ick" or white spot to me, happened to my fish, its a parasite that breaks through the scales of a fish and sucks on the blood, once its infected its usually fatal and nothing can be done, but you can still get some ick control.
