Getting Desperate.... Please help!!
I think my fish may have some kind of parasite, but I don't know how to kill them! A while back I noticed that the tank had Ich which I treated using the heat method. After that I treated with Jungle Parasite Clear, Jungle Parasite Clear, and the latest treatment was Jungle Parasite Guard, all at about 3/4 strength. I also used a mixture of Pimafix and Melafix along the way.
My fish are STILL scratching up against things and they're incredibly jumpy. I used to be able to walk by the tank with no big issues, but now the fish almost always go crazy when I walk by. Just a few minutes ago I threw in some shimp pellets and all was well until my Pleco came out. I'm assuming he freaked out one of my Gouramis who in turn started flipping out and scared the rest of the fish including the Pleco who raced back to his cave and slammed into it. One of my Gold Gouramis ended up flying into the corner, slammed up against the heater, and back into the glass. You could hear the water slapping around. It scared me, I can imagine how much it scared them!
I'm afraid of what's doing this to my fish and I just want it to end, but I can't figure out what I'm doing wrong. I'm frustrated and want them all to be healthy again, but I really have no clue what to do. There are no visible signs of a parasite and my parameters have been stable at Ammonia + Nitrites = 0ppm, Nitrates = 20ppm, Ph = 7.8.
Can someone please help?!
