I bought a small Coral Beauty on Saturday and have had her in a 10 gallon quarantine tank since then. The store had all of their new fish in a lower salinity system since they came that way from the shippers (she had arrived last Monday) so her quarantine tank is at 1.020. The quarantine tank has a few chunks of live rock from my main tank, a ball of chaeto, some filter floss from my main tank, a powerhead and a heater. She was fine over the weekend and was eating last night. I woke up this morning and she's seemed to be acting funny, alternately swimming near the surface (she'd been mostly staying near the chunks of rock up until this morning) and just resting on the bottom breathing heavily. I tested the water and it showed .25 nitrite so I quickly did a 2 gallon water change. I redirected the powerhead more towards the surface to try to oxygenate the water a bit more. Half an hour later she's lying on her side gasping. I've since done two more 2 gallon water changes and the tests are showing 0 nitrite, 0 ammonia and 0 nitrate. Due to the multiple water changes in under an hour the temperature in the tank dropped about a degree and a half. Her condition hasn't changed she's just lying on her side. What else can I do? What did I do wrong?? Any thoughts would be greatly appreciated
