My betta fish won't eat, isn't growing, and keeps floating. Help!

Pet's info: Fish | Unknown - Fish | Male

Hello! My pet male betta, Mr. Bubbles is rather small and doesn't seem to be getting any bigger. He also tends to stay under my plant in his bowl and tends to float to the top quite a bit. He's healthy otherwise. He's a picky eater too. I'm feeding him Bette Bits and freeze dried blood worms. Sometimes he doesn't even eat it or eats it then blows the pellet out. I've had him for close to 6 months.

Try feeding Hikari Micro Pellets. The smaller size may make eating easier for him. You can also offer live blackworms as well as bloodworms. Confirm adequate water quality, proper water chemistry and adequate temperature. Bettas do best between 78F and 80F. If he is in a bowl or tank with no filter, weekly (or more frequent) water changes may be necessary.
