K thnks. So 50% water changes how often? Would tap water be ok. to use? Its like filtered tap water, and then conditioner. How much conditioner do you suggest I put? Would salt help too, and if so, how much? And if I do get a test kit, how do I get nitrites and ammonia down, just water changes? ALso, the fishes gills are a little pink, and are pretty open, is that also probably form ammonia?
