I was on vacation and the house sitter grossly overfed the tank.
I pulled everything out that I could immediately (plants/rock/driftwood- which all had huge mounds of decaying food) and did a 50% water change, followed by four consecutive days of 25% water changes. Well that cleaned things up a bit, but it seemed like ich might be an issue, so I treated the tank with ich-noch and acriflavine. Prior to treatment I tested the water and the values were perfect (0 ammonia/nitrite/nitrate). The instructions said take out the filter so I did, and two days later two of my four platies died. So I immediately put the filter back in and treated with bio-boost. The other two platies are still alive, but sick with a bulging-out clear growth on their eyes. When I rasied the temp in the tank, one of them suddenly started swimming more normally. It's been a couple days since then and neither is doing well.
10 gallon tank, 2 orange platies
87 degrees, Penguin bio-wheel power filter (hangs on back of tank)
water test yesterday- 0 ammonia, 0 nitrites, 5ppm nitrates, ph 8.1
25% water change last night
It doesn't seem to be eye cloud-the "growth" is clear.
What can I do to try to save my fish?
