So unfortunately I didn't know about the nitrogen cycle when I bought my fish and his tank so I had to do a fish in cycle and he has developed fin rot. At first I thought it was just a small fin tear but it is slowly creeped on to his other fins. The tank is fully cycled now but I need to know what to continue doing to help his fin rot. While cycling his tank every other water change I would try and put a little bit of aquarium salt in the water should I continue putting salt in the water or just let it try and cure itself? I've also reduced his meals to every other day, once a day, And much smaller amounts.
