Fish Fins Broken!

[falcodarkzz]

I have a small nine gallon tank, with mollies guppies and a dwarf gourami in it.
Recently I spotted a guppy and mollie with torn fins, does anyone know what the cause of this is? an aggressive fish, or perhaps a disease?
I have never really seen any of the fish attacking eachother.

Should never keep guppys with gouramis, i'm afraid you will have to decide which one to keep, as gouramis are fin nippers.
