I just joined this forum. I had a Betta that had bloat too. The best we could do was lower his water level and try to let him pass it. I didn't(and still don't) know much about this type of problem as he was my first fish. If it happens again, the most I can say is to give him fiber(peas) and lower the water level. Some bacterial/fungal medications might help to prevent other problems.
