My betta is swollen and pine cone looking, looks like he swallowed a pea. I'm pretty sure it's dropsy. What I want to know, is is it contagious?? Should I treat whole tank just in case(community), or put him in fishbowl and treat by himself. He is in a 10gallon, (my only tank) but I do have a fish bowl. Please help, I love the lil guy.
