I fed the girls in the sorority today, and was quite concerned, I couldn't find one. After stepping back I saw an odd shape on the betta log. One of the girls had breached herself. I poked the log down and she twitched about, I was fearing the worst. I scooped her out of the big tank and put her in a small QT tank with some extra stress coat and draped a cloth over her. It's got a small heater, and I didn't add any AQ salt in, she's breathing so hard and it looks like she's trying to breach herself again.
Temp unknown, should get to 75-80 when the heater warms it up. In about a half gal of water, Stress coat. Will do daily changes. I offered her a piece of frozen blood worm but it's not even registering. Will be doing daily changes, and just hope she can go back in with the girls. If she lasts through the day I'll add a bit of AQ salt, probably start light at about 1 tsp gal.
Don't know if there is anything else I can/should do. No tannins, but I did cover her tank. IF nothing else please send fishy healing vibes.
