I set up my 29 gal. tank in the middle of June. About a week later, I got three small goldfish. About a week later, they all developed Ick and even after treatment they died. I allowed the tank to cycle with the same water for three weeks before attempting to add any new fish. Last Sunday I got two goldfish, hoping that two would be easier on the tank than three. Well, yesterday one of them died and today the other has white fuzz on its head. I've tested the water with the 6 in 1 strips and everything is in the acceptable levels. I'm at a loss for what to do. If this fish dies, what do I do with the tank? Should I dump it and start new? I'm thinking it is the goldfish because I've had other fish before with no problems. My last tank was stocked with Gouramis and dragon fish, and they were fine... I'm beginning to get really frustrated.
