Is this ich? This fish has a few white spots on its top fin and a few more on the other side. Another one had a white spot similar on her head but it's gone now a few hours later. Wondering if I should slowly up the heat to 86 and do the whole heat treatment to the tank and hopefully nip this early. It's a 16 gallon with only 5 Galaxy rasboras/CPDs in it. Also my two females are kind of plump. Full of eggs?
