Yep the caudal fin will grow back. I've had bichirs that had fin injuries and the only one that didn't quite grow back was a bent dorsal spine/fin. I treated mine with Ocean Free's General Aid Special to help with the healing and avoid infections, but I'm sure other members have other methods too (ie water change, other meds, change water temp, etc)
Thanks for the advice. ...
