i have a male beta and i noticed that his belly is very swollen. is he sick?

Answers:
You might want to call a fish veterinarian or you might call a local pet store that deals with fish. They should be able to answer your question over the phone. They may very well ask you other questions to get a feeling for what the fish looks (does it have unusual spots, etc) and acts like.

It might be the food quality.

Found this on a forum:
Could be dropsy or It might be TB, the symptoms include swollen abdominal area. In fish, this is due to the swelling of the liver, but to us it just looks like the fish has a swollen belly. Fish TB, or mycobacterium disease, is transmissible to humans, so care is required. Wear waterproof gloves and disinfect your hands/arms (and the fish net) every time after coming in contact with the fish, the water, or even the filter media.

(found this info at the forum link below)

Unless you see other signs of stress, you are probably over feeding him.

quick get regular table salt pour about a table spoon in his tank then bake him a bean he might just be constipated

He is sick.
have many case like this finally they are dead.

sickness called bloat. bacterial infection needs to be treated asap or they die. tanks need to be kept clean and chlorine removed.

Well it could several things. Bloat from over feeding, contipacion, or drospy. The 1st 2 are easily curable. The last rarely once the novice notices. (Even with early detection it's often too late.)

Bloat, and contipation can occur if you over feed, or feed blood worms too often. (Blood worms are good, but not ever day) Double tails are more prone too this. You should stop feeding for 2 days then feed a cooked peeled pea. This should clear the digestive track.

Dropsy is not a disease but the result of organ failure. This could be cause by disease, or ammonia/nitrate poisoning. If the scales are starting to stand out the fish is goner. Otherwise you can keep the water clean, temp stable, and treat with a broad spectrum antibiotic. In the case of dropsy you need the big guns that means trisulfa.
