I bought my sweet Vladimir today, and he has 1 inflamed gill. I guess I didn't really think about it when I bought him, but now I'm noticing it. And it's just one inflamed gill, not both. He is in a 1 gallon tank, with a light, a heater, and the water has been treated with a conditioner. He has rocks, and a little "log" to hide in. He looks fine with no "cotton" or strange bulges although he does seem to have a "betta beard." Why might he have only one inflamed gill? I bought some "Betta Fix Remedy" which is a Betta Antibiotic (aka Ampicillin) but it will arrive in 3-5 days. Did I make the right choice in purchasing that; do you think I should get something else to fix him? He still has an appetite because I fed him today and he definitely ate the 3 pellets I gave him in under 5 minutes.
