No--never had any fish bite me in many years of fish keeping--yet; knock on wood.
That is because of luck or happenstance, I didn't or don't have fish that bite, or were too timid to bite, and/or maybe seemed to be aware (in my mind), that you don't bite the hand that feeds you, in some cases. Ha. ...Oh boy, here comes that fish from beyond the water that always has the good stuff around it.
I have a quite a few different species.
Like I said I have probably been lucky. I have two cichlids that are species potential, potential monster biters. One I play tag with outside of the tank. It hangs around when I am cleaning algae. No attacks.
The other cichlid flees when I put my hand in the tank. Both are decent sized fish--5 & 6 inches, with heighth and girth and aggressive toward other fish.
My Senegal Dragons have never tried to bite me. They are 6 inches.
I have had most of my fish since they were tiny. I don't know that this has any bearing.
I have read that some fish can be trained. In some cases it may be too late, or just not possible. But in some cases it may be possible. I have read that feeding on one side of the tank while doing maintenance on the other works in some cases may work. Some fish are just too territorial for this.
I have several various brand automatic feeders that I use when I am away for a weekend. Some are simple twice a day mechanical/battery operated. Others are digital that can be programed for any number of times and days. Some are quite reasonably priced. (Look up cheap--that doesn't mean inferior quality.)
My buddy had a big territorial freshwater angelfish that tried to attack and/or bite him every time he fed it or put his hand in the tank for maintenance. I bought him an automatic fish feeder. He just never bothered to use it.

<<< >>> There are any number of various feeders and automatic feeders.> I saw online, a floating fish feeder that might keep them busy for a few minutes. Then remove the feeder when you are done with maintenance, or leave it if you you have really ferocious Barracuda wannabes : Magnetic Floating Fishing Ring by Two Little Fishies at SaltwaterAquariums.com. I would have put in the full address, but it wouldnt let me see the full address. It is supposed to work for any kind of food; flakes, powdered, pellets ect.
