torn pectoral this is silly I.m sure but can't find an answer anywhere

[Robd]

Dalmation molly's pectoral fin has benn torn and has two slits (making three seperated parts) I can't see how it could posobly grow back together could it? Is this a bad thing or will it have a negetive effect? she seems to be swimming fine all three sections are moving

If you keep the water really clean, they will grow back.
My betta bites his tail fins off constantly and they always grow back.

lots of water changes... that'll fix it right up.

Pristine water conditions, lots of water changes and don't forget to add dechlorinator.
