I was given a tank and it had a few fish in it, i've sold some on but decided to keep a couple of large male Convicts, I thought one of them had worms as it had red/pink stuff coming from its anus but now i'm not so sure, it looks more like a solid mass than single worms bunched together.. Tried treating with Kusuri wormer, added a second dose today (4 days later) and it hasn't changed any.
