I just noticed today that my Betta fish's stomach looks a bit swollen. Not as bad as a lot of the fish you see when you google "bloated betta", but, still, nonetheless, looking bloated. He's less active than usual.
No heater, no filter, I know, I know. But guess what? I have a tank(10 gal) set up right now with a heater, filter, etc. I figured I'd put him in it tomorrow or something.
I just started giving him Omega One pellets for bettas. I realize I should've let them sit in tank water, absorb, and then cut then in half or something because they are small betta sized pellets but they get BIG when they're sokaed in water.
I have pictures but they don't do much. The flash is a little distracting but if I didn't have flash on, he's a dark fish so it wouldn't really show....
You can see it best in that photo. What can I do to help him? Do you think it's serious? D:
