For the past 3 weeks or so, my 1 year old female betta has a very round stomache. I don't think it's dropsy because her scales don't look like they are popping out. She is eating and is not pregnant, but tends to go on the bottom of the tank a lot. Someone said that it could be a tumor... but I don't know how to treat it.. :(
I took a picture of her in 3 different angles. She's obviously knows I'm taking pictures of her..
The betta lives in a 5 gallon tank and lives.
