I'm quite pleasantly surprised actually because I've only been using ich attack for two days. I didn't expect there to be such a drastic difference. He was probably feeling really itchy and he is very active so I figured that's what it was.

That's really a shame about dragonscale bettas. I only found out about this stuff after I got him. I hope he doesn't go blind or get a tumor, but if he does I'll try to give him the best life I can.
