I have betta that is really swollen for about 2-3 months now. it just happened very fast. initially i thought it was dropsy (i read that it could manifest as a severe swallowing, without the "pine-cone" effect), but the fish is acceptably lively, it eats every day, is active, can swim in all the areas of the tank with no problems, and survived for 3 months. with dropsy i doubt that would have happened.
when i say severe swallowing i mean that if i look at it face-to-face, its sides are about half it's head on either side and below. i believe the body volume has at least doubled.
