Our new Ropefish (from petland) that has been in our tank just short of a week now is standing on its tail and sinking to the bottom of the tank. It hasnt eaten when you hold frozen food in front of its face. Mostly since we put it into the tank it has either hung itself over the heater or around the back of one of our filters. Earlier when I first noticed it gasping at the bottom I used the net(read: hand) to prop it up and hold it near the top where it would burp air bubbles and then swim for a few seconds. I've left it alone for a while propped up near the heater where it can get air. Tank parameters are pretty good. 5 buenos aires tetra 3 mickey mouse platy 1 ropefish 24 gallon (waiting for a bigger one) Nitrates 20ppm Nitrites 0ppm ph 8 ammonia <.25ppm I did change the filters and wash the bio screen on one filter this week due to build up. If anyone has any ideas I dont want to lose this fish. Makes my tank.
