Do fin tears heal or grow back?

Yep. I've had many fish get chewed on they end up ok.
 
Yes, to the best of my knowledge. Anything I have put in with my piranha has had its tail bitten off and they eventually grew back.
 
Depends on the damage. My Jag, when it was little, got it's tail fin completely bitten almost the the base by my Pearl Gourami. It got bigger, killed the Gourami and the other Jag I bought it with, and grew back it's tail fin. I had a betta that was badly beaten up by the same Gourami. The tail fin never healed.
 
I have a pleco in a african cichlid tank and his fins get torn up or chewed up occasionally and they always grow back in a couple days. But like other people say it all depends on how extensive the damage is.
