Last week I put an angelfish (and others) into a new tank. I had been seeding some filter material but the tank mini cycled. Ammonia touched 1ppm but nitrate appeared yesterday. I have done three partial water changes in the past week smoothing it over.
I had been watching the angelfish keeping to one side of the tank, and seeming less than enthusiastic about the change.
Today I noticed his dorsal fin fraying at the top, kind of like a paper chinese fan that has been opened too many times, with small sections falling out. I noticed a furry whitish fungus like growth at the tips of the spines.
This evening I transferred him to a 2G QT with a standard dose of malachite green and 3tsp/G of marine salt while I did a partial water change on the DT. After half an hour, I upped the salt by a further 3tsp/G and waited another half an hour before putting him back.
I decided to ramp up the display tank to 1tsp/G of salt, hopefully calming them a little and helping with the nitrite.
Is there anything else I may have missed or could do better?
