Ielieve whatever happened started on the car ride home, he was not like that when i picked him but when i put him in his new bowl i noticed it... possibly curled his fins up when he was in the small space from the bag? His bottom fin is now curling though, I dont think its water quality, He had a complete water change 3 days ago... I found a large pictue of a fish whos top fin looks like it might have the same thing, though on this one the bottom fin is not curling. The very tips on my fish look a little lighter than the rest but I think its just the coloring...
if you click on this picture to zoom in and look at the end of its top fin, it looks like it may be tangled like my fishes fin is.
I think he is happy.... they said that happy male betta put bubbles on the edge of their bowl/tank for mating purposes? He made some bubbles and they statyed there.... He eats great and seems to be very curious, and often goes after his own reflection until he hits the edge and realizes its not a fish
