| || | Sick Yellow GloFish & Nitrite Problem - Need Advice
I have a tank of four zebra danios, one being a Yellow GloFish. As of the last two days or so, he's been looking pretty sickly. He only swims to the top left and right parts of the tank, and seems to stay there all day - he never socializes with the other fish. The other three regular zebra danios swim about the tank, eat voraciously, and generally look good - not my yellow one. He also seems to be very thin - I tried to feed him extra, but he refused to even eat the tiniest bit. I tested the water, and my nitrite ion level is through the roof - the strip pad is bright pink. Are my plants affecting this crazy shootup of nitrite, or is it okay, and just the fish is sick? What do you recommend I do?
If I need to remove Mellow Yellow (my parents renamed him xD), then I can do so, but I don't have an isolation tank. Hope he doesn't die!
