hey guys! It’s been a while since I posted here, but recently I purchased a pearl Gourami. After 2 days I noticed he had some white spots on the fins and head. I thought it was ick so I turned up the temp to 89F. This morning he is acting fine but 2 is my cardinal tetras died. I checked my parameters it was 0 ammonia 0 nitrite and 10 nitrate. I also did another water change as well but the temp went back down to 85F. So my question is: Do I just keep up my tank temp at 89F to get rid of the ick? I don’t want to use salt because I have Cory cats and otocinclus in my tank. I’ll try to get a photo of my GouramI later if someone can actually ID if my GouramI has ick. Thanks!
