My jack has developed a bad looking tail it is clamped, ripped and the center looks whitish/ raw. Gills are slightly red and he hasn't eaten well since being transfered from a 42 hex to a 75 with just him and a female. I don't have another tank to use so I will have to dose the entire tank ~80 gallons 75g tank and 29g sump. Front fins are also slightly ragged looking. I previously tried melafix/ pimafix but those didn't work so I think I need something stronger. what would be the best way to dose this tank? I really don't want to lose either fish. I've been doing 50-75% waterchanges ever other day and now have my drip system setup again. Will be running to the store here soon.
