I bought two male Bettas from ebay about a month ago. One is very healthy the other seems to have had issues from the start but has recently become very sick. Main issues are lethargy and one of his gills seems to be swollen and does not fully close.
I have in in aquarium salt and he is so much better but his gill is still swollen open. I seem to recall that i noticed his gill being odd maybe over 2 weeks ago. Plus side is he is now swimming about and is not nearly as lethargic but his anal and dorsal fins are clamped his tailfin is normal not clamped.
Anymore that i can do for him besides the aquarium salt and oak leaf tannins that I have been treating him with??? Right now he is in a QT Kritter keeper.
Will try and post a picture this evening. Like I said he is better and is on his 6th day of aquarium salt with daily changes. I am worried but I have hope
