Crowntail Betta Ripped Half Tail Fin Off

[Gurglar]

So I bought a crowntail betta about 2 months ago and specifically bought him cause he had the best fins i've ever seen at my shop really long and full. Now i've just noticed he doesn't look quite the same and realized his tail fin has been ripped off its about half as small as it was

So i'm just wondering if it will actually grow back or will he have the short tail from now on?

So disappointed cause he was beautiful now the poor guy has half of what he had I knew I shouldn't have had the piece of wood in there that I got

It will grow back, but what have you got in the tank with him?

Nothing but a small bristlenose, they both just ignore each other.

My guess was the wood I have in there as it has tiny thin branches that stick out everywhere that he could have got caught on and I only have real plants in there so he can't get caught on them.

Yes they definitely grow back, though they may look a little wonky. The water must be pristine, even more than usual (do an extra water change each week )and also a quarter to half dose of melafix ( not full dose, bettas can be sensitive to a full dose ) will help heal his tail even quicker. I've used it very successfully in the past.
