My betta has bulging eyes, white film, and fin rot. What else to do?

Updated On September 23rd, 2025

Pet's info: Fish | Unknown - Fish | Male | 2 months and 10 days old | 0 lbs

My betta fish is typically highly energetic and had a full, long tail. Recently, however, his eyes have become enlarged, almost bulging, and has had a white film over him. Just last night I noticed his tail is very sparse, so I ran out to get a medication for ich, treated the bowl, and he seems to be better today, swimming around instead of just laying on the bottom, and actually eating. I just want to ensure there's nothing else I should be doing. Thanks!

Ich typically presents as tiny white dots all over the body. The white film may have been a fungal infection and the eyes may have been affected by a secondary bacterial infection. The Ich medication may have had an ingredient(s) that treated the infection even if it wasn't Ich. Maintain water quality and temperature (78F - 80F) and dissolve 1 teaspoon of plain aquarium salt (NOT table salt) per gallon of water into the tank. This will aid healing and can treat minor bacterial/fungal infections. Treat for 7-10 days then perform water changes to decrease salinity. Use only aged or conditioned water to prevent shock or stress.
