Ive had a Red Pacu for a while now and he and the 2 Blue Gouramis out grew the 29g tank they were in so I spoiled myself and bought a 150g tank. (boy was I in for a extensive piece of work) But anyway, the tank came down with a severe case of Ick. I lost 2 Irredescent Sharks to this due to the treatment but I was triumphant! Got everything undercontol, or so I thought. The eldest of the Pacus that I have has come down with something. Im thinking its a fungus of some sort. Its on his upper lip and has grow significantly in the last week. It kinda looks like a white puff ball on his "nose". I thought it was an ulcer but I did a little research and narrowed it down to some sort of fungus. Is there anything someone can tell me that will assist in the remedy of this. I would be rather upset if I lose this guy to something that could have been prevented rather easily. If needed, I can get some pictures posted. Even though he is camera shy Thanks!
