Anybody know what I can do to help out my betta? He's got a blown tail, not sure if he's nipping it himself or if he has fin rot. He's in a 10 gallon planted tank with 3 small Cory cats and a small bristlenose pleco. He's pretty content. Likes to eat straight from my hand. Just don't know the cause of his fins. He's a halfmoon and is starting to look like a crown tail.
