I recently got two betta's (in separate tanks) from a friend who just couldnt care for them. My red betta was doing fine :( but now all of a sudden he/she has a huge bulge just behind and under the front little (fins?) and gills. It looks like it is going to explode . At the very bottm there is another small buldge that is clear/white with what looks like small bubbles or scales. I just cant stand to see him or her suffer. If there is anything I can do that would be great. Please help!!!
