i have a 1 or so year old beta fish also known as a Japanese fighting fish, and it is all swelled up , only swimming on the tops of the water and has wat looks to be a small hole in its side. my brothers fish did something like this and a week later it died, and ive realized my fish has been more like this over the course of a few days. wat wrong with my fish? and is there any thing i can do to make him better?
thanks for the help.
