I think I'm in the middle of a fish crisis. My tank's nitrite level is very high, even after a partial water change daily, and today, a 7/8 water change. I have moved my two rosy barbs into a separate jury rigged tank (consisting of a rubbermaid water dispenser and an air hose to keep the water from stagnating) and I put my three rasbora heterotropha tetras and my pleco back in my tank. The tetras, however, are forming small air bubbles on their fins and sides. I was wondering if this could be related to the nitrite level or if I was just looking too hard to see if anything was happening to my fish. I am leaving tomorrow to go away for the weekend and will either be leaving my fish uncared for, or cared for by someone who has no experience dealing with fish. Any suggestions on any of these problems?
