So I have a 58 liter tank an ehiem classic 250 which as a slower flow than most also hoping on getting a tidal 35 or 55 to help it out a bit it seems to be struggling. It's stocked with 3 albino corys one bristle nose and two pearl gouramis. One of the pearl gouramis has a sort of fluffy small white spot in its eye and what looks like fin rot on its top fin. I am treating it with interpret anti-fungal and fin rot. And just wanted to make sure this is what the disease was. Also adding interpret equilibrium salt. Just wanted to make sure it was fungus and not ich or something like that.
