I was just wondering the best way to go about treating ich without raising the temperature in the tank. Unfortunately the heater I have in my 5g tank does not have a dial to change the temp of the water. It is set for 78F and that is where it stays. I believe one of my bettas has ich. He has white spots that look like salt all over his head and he has been laying down quite a bit today. I was going to start with 50% water changes every day and go from there. Is ich a fungus or a parasite? I have fungus clear, parasite clear, and jungle labs anti-parasite medicated fish food, but I am unsure which to use. Any other suggestions are greatly appreciated.
