Betta looks like stomach is filled with a bubble

One of my bettas stomach's looks like it has a bubble in it, it is way fatter than it should be. I can also see the inside because the skin is stretched so thin It is clear on the inside and the betta appears not to have any swimming difficulties. Anything I can do? It's been this way for a while

When i first read your post, it sounded like your fish has a tumor. But now, it could be a number of things.

Is your fish like that all the time? or does he have days where the swelling goes down?

If it subsides some days, it may mean that he is becoming bloated from the food you are giving him. If that is the case, then you might want to change the food you are feeding him.

Also if you feed him every day with lots of food, I hate to say it, but thats ONEEEEEEEE FAT FISH!


Your fish could also have a swim bladder problem, but that would involve swimming difficulties, such as floating to the top (being unable to swim down) or being unable to swim to the surface for oxygen.

Hope some of this helps, and let me know some more about him

i agree, try fasting him for a few days and feed him the magical pea

I fasted him for a week It's been swelled since early july, and seems to be getting worse. It looks translucent, so I think it's trapped gas It has gotten worse since this pic was taken

argh that looks really uncomfortable. I had a betta that looked like that a few days after i bought him, turns out that he was just constipated and the pea thing cured it

it could be some internal parasite/bacteria infection?
