I just moved my male pearl gourami to his 20G QT this evening because he hasn't eaten in a few days and he has been clamping his fins. In this tank (probably because it is so well illuminated, especially without gravel and plants on the bottom) I see some very, very ,very small white flecks around his mouth. I am assuming ich or velvet. My water temps have been averaging 80F in my main tank. I turned up the heat to 82 in my main tank and the QT. I also added salt to the QT. I also put a baby platy in, kinda like a test control. Should I crank up the temps in both tanks tomorrow? How high can the rest of my fish tolerate? The fish in my main tank are fine--I'm cranking up the heat in that tank, assuming that if this is a parasite they are at risk .
