So yeah -that was the beginning signs of lymphocystis. If you have a fish that has white growths that are kind of tumorous looking they might have it. I brought it into my tank with that emerald catfish and it spread to my electric blue acaras. Crazy water changes has reduced the signs of it to almost nothing but from what I've read all my fish probably have it now.
