I have a 10 gallon tank. Currently all my other fish are swimming around happily. All except my rainbow shark. He has been "floating" behind the heater since I put in a new TopFin 50W.
I used to have a shatter proof MarineLane but even tho I had it set to 82 degrees (It can get cold in the office over night) the tank would stay around 74 (during the day) and that was with the temp tag right by the heater.
I put the new TopFin in and now the temp is around 84 during the day and all my other fish are swimming around happily instead of hanging around the heater. But now my Rainbow Shark is floating behind it and looks to be dying.. Barely comes out to eat, he used to swim around the bottom all the time. He doesnt look an different (growths or spots or anything) that I can tell.
What could be wrong? Is he too cold? Sick? I tested my tank and all the levels seem perfect. And once a week I do a 1 gallon water swap. I empty out a gallon, then fill up a gallon container with the tap water at the office, then add "Stability" by Searchem to the container and wait. then add the water.
I usually feed them twice a day with flakes and sometimes mix bloodworms in.
