I have 10 flame tetras 11 espei rasboras 3 furcata rainbowfish 2 otos 4 amano shrimp 2 nerite snails Planted tank I noticed a white salt-grain spot on one of the rasboras two days ago, and now I'm noticing a spot on 2 of the rainbowfish. So I'm betting on Ich. I think once before, gosh it's been so long, I used something that had malachite green in it for Ich. I also remember raising the temperature to 84 or 85. And doing this for two weeks, I want to say What's the best way to deal with Ich tank-wide with the inhabitants I have in there?
