Betta with shredded fins?

[coolcucumber]

hmm. The end of my bettas fin looks shredded. not too badly, but enough for concern. Also, his dorsal fin looks like its been rolled in on itself, and its stuck like that.Not sure whats going on, hes been in a 5gal split with another betta who had the same problem, but died. hes currently in a jar with aquarium salt, floating in the tank.Any ideas about what happened?

Either fin rot or something sharp.

Make sure the aq. salt is the right amount/gallon and make sure changes are frequent when youre using it :D
