This afternoon I noticed my betta Mr Bojangles doing his flaring dance for me, and only his left gill flared out. A second or so later the right one flared out. This happened every time he swam by me and did his flare dance. I looked closer at his right side, and there's a whitish line, (not spotty like ich) about 1/2 cm long, on his gill. Bo is in a 1.5 gallon heated betta bowl at work, I've had him about 3 months. I know bowls are bad, but he's at work and my options are limited. I do a 100% water change every week, and apx 20% changes 2 or 3 times a week. Has anyone seen this before? I hate to exaggerate, but I'm crazy about this fish and I don't want him in discomfort and I CAN'T lose him!
