Hello; I seem to recall that fisheries biologists would notch fins on hatchery fish to be released into the wild. .
Salmon hatcheries clip off the adipose fin they hatch so when they return to spawn they can count how many versus wild return back. They have a diversion off from the river that guides the salmon through a narrow passage that they have a window to see the fish pass by they do a visual count. Not all Salmon go through it but they get a percentage that do which gives them the percentage they need to come up with how many return each season.

I wouldnt. If it's just for aestethic it's a bit selfish to start cutting the fish, no? It's not even like it's just the fin... it's bone too... that'd be like cutting off a finger. Kinda like cropping a dog's tail. Don't do it.

And whoever said that putting the fish in a rag because the slime coat will stick and it wont move... that's one of the worst things I have ever heard. Never heard of when people go fishing, catch and release, that grabbing the fish in a rag or letting it flop in sand or dirt is a huge no-no because it removes the slime coat, and they get sick?

If you do attempt it you do want to take care not to rub off there slime coat. What I do is lay the fish on plastic bag thats laid over on a soft towl and hold it down with the plastic bag or latex gloves if you have them. You got prepare everything before have a plan so you can do it quickly. You can also pour Seachem Stress Coat over the fish just before you put it back into the tank. I have had to remove stuck objects from fishes mouths many times. I have had fish have a cyst on the fins that would never go away so I cut out. Just prepare everything have a plan what your going to do how your going to do it and do it quickly.

oh and i dont mean cut the whole fin off, to be more clear its probably about half an inch before the kink appears. i would just have to cut through the bones that go through the fin. I wont do it anyway. it would cause too much bother.
"its just a bother" lol.. dont worry about the fact that your severing a bone from a living creature fully capable of feeling pain. Im not against it i just think that was funny lol

Maybe not in the fins themselves, but in the bones, yes.
And saying that it's just the fins doesnt really fix it, everyone has lost a fish from nipped fins, wether it's from stress or infection.

Don't do it. Sell your fish if its appearance bothers you so much.

A picture might help inform this discussion.

I personally see fixing a twisted fin as setting a broken arm. People on here make unfair comparisons to cutting off fingers and arms. If you don't cut bone/spine you are doing no such thing. Fingers don't grow back fins do FYI.
