What is wrong with my fish!! Fish expert needed!?

the temperature is too high. My fish began to do the same. Bring the temperature around 74-76 degree farenheight. Check for amonia, nitrite, and everything else that is listed on the testing kit. If you don't have one, get one. You are going to need it now more than ever since you just started your tank. If any of these levels are high, the best way to bring them down is to do a water change. Only take out about 1/4 of the fishtank water and replace with fresh, treated water (aquasafe declorinizer). If it is reallllllly bad, then remove 1/2 of the water in the fishtank. Never remove all of the water because the bacteria at the bottom of the tank needs to stay there. Also, do not change the filter. the bacteria live there as well. Fish NEED this bacteria to survive. Hope this helps. You might want to add some ice cubes in the tank to bring the water temperature down quickly.
