The same way you know you are who and what you are. They have evolved to do it just as all other living creatures do it. Why should fish be different?
This will depend on the type of fish you have, as some have round fat bodies.If it is not due to the type of fish, then it is possible that your fish is constipated. To help your fish, you should fast it for 3 days, then feed it cooked de-shelled peas twice a day for 3 days (this will only be a few peas). This should help your fish poo and may reduce swelling if constipation was the cause.
leave it there. It won't harm your fish.
