Will a chewed up tail fin regrow?
 

I got a sunset gourami from the LFS, but his tail fin has been chewed up. (They kept the lot with some tetras who chewed up everyone's tails)
Will the tail fin regrow?

Yes. His tail will regrow. No worries. Just make sure you keep the water parameters good and feed him a diet high in protein.

Thanks Izzy! I am relieved to hear that.

I have a Pearl Gourami who's entire tail disappeared over night once. It completely grew back over time. Altho it's a little crooked. Never did figure out who was responsible.
