Aquarium Advice FINatic
mfdrookie516 said:Nitrite poisoning wouldn't cause 'white lips'. The fish would probably be gasping for o2, since nitrite does some fancy chemical term to prevent oxygen from being taken in to the blood stream. Aquarium salt or prime is a good method to help reduce nitrite toxicity in emergencies. Water changes are probably better though.
The 'white lips' sound like columnaris, which I've had the unfortunate experience with before. It usually starts with the lips, then moves to patches on the fish. Google it and see if that may be what you're working with. If so, lowering your temp 6 degrees and adding aquarium salt are a good idea, as well as treating with a med that targets gram negative bacteria.
Nitrites are ok though , its the NitrAtes that I'm worried about :/
