I think my betta might have gill flukes. His breathing is heavy, he has to take air from the surface every few seconds, and he is twitching. He is very lethargic and doesn't move, he just sits at the top of the tank on a floating plant. His fins are clamped. He is still eating, however.
He was fine this morning when I fed him but when I came back he was almost completely white and not moving. He has gotten his color back since then, though.
Tank is 10 gallons, heated to 80 degrees. Water parameters are fine. I do 20% changes every other day and I did a 40% today and added a tablespoon of salt.
How do I combat gill flukes? I can't find a lot of good solid info on how.
