Hi Keepers_girl, I'm glad to hear the betta is getting better. I give my bettas peas once a week. I'm not sure if more frequent pea feedings are ok. I would wait at least 5 days to give more peas. (Menagerie, TankGirl -- what do you think?)
I wouldn't feed tonight or tomorrow. Do you have any daphnia? I would try some daphnia on Thursday or Friday, and then maybe some more peas on Friday or Saturday if it looks necessary. I have read that daphnia can help digestive ailments also. I feed my bettas freeze-dried daphnia twice a week, along with the peas once a week.
