What is hypo exactly?For what its worth im NOT a fish medic and learn everyday. But its hard to make out but I see the black in the gills and the redness i think is on the fins. That could be bacterial infection with high nitrates and state of tank. So there could be two things happening.
And alas there is not a cure all IF this is black ich in the gills Praziquantel or hypo would cure that.
The other is bacterial which I think rally pro could potential fix it. again not a medic I just like to help where I can
