Fin rot can kill quickly if left untreated. Clean water plays a critical role in treatment and recovery. Perform daily partial water changes using aged or conditioned water that is temperature matched to prevent further stress or shock. Bettas do best between 78F and 80F. You can continue to use the bottled treatment as directed. Add a bit of plain aquarium salt (NOT table). As well to aid in recovery. Dissolve 1 teaspoon of salt per gallon of water in a cup of tank water and gently pour it into the tank. Treat for 10-14 days then reassess fin condition.
