I had to cut about 1/3 of a fin off my pictus cat, he had gotten it massively tangled in the net, and was ripping the skin around his fin 'joint' trying to get loose. He did just fine, took a while to get used to the missing part and for it to heal, but he did fine.
Is the barbel open, or just bent? If it's open, from what I understand (and did to mine), turn the temp up about 3 degrees and add a little salt to the tank, and add some StressCoat.
DO NOT DO THIS UNTIL SOMEONE ELSE HAS CONFIRMED IT THOUGH!!
Sorry, I didn't mean to do the caps, but didn't know how else to make it noticible. I would feel horrid if that didn't work for yours, and it died or something. Please, please PLEASE make sure that someone else confirms this before trying it!!!!
Best of wishes.
