Does my betta have popeye?

[ialcaraz]

Hello fellow fish keepers!
I noticed that the eyes of my betta, sasuke, have looked a little popeye-ish. Water parameters within normal limits, he’s housed in a 10 gallon with 5 Pygmy Corrys, temp steady at 78 degrees, eating fine and swimming fine. He gets 25% percent water changes every 3-4 weeks. I’ve added some pics and apologies if they aren’t very clear. If this is popeye, would u recommend BettaFix and Aquarium Salt?? and should I move my betta into his old 5 gallon for treatment or will my Pygmys be affected? Also, excuse the messy substrate, it was feeding time for the corrys.

It doesn't seem really big, but I have a hard time with fine detail in pics generally.

Best chance for popeye is excellent water parameters. Water changes for a little while, every day say a week, then if it seems to be getting better then keep water changes every other day, and then every 3 -5 days.

If it does not seem better with simply bettering the water quality, you may need medication for internal bacterial infection.

Also check the tank for pointy driftwood or other things he might bump it on.
