I don't know how they tattoo but I do know they use it without any pain killers or tranquilizers.
That is horrible! I just googled it. They do it a few different ways. Injecting the dye with needles, dipping them in caustic liquid that dissolves their slime coats then dip in dye, dyed food, lasers. Fish are pretty enough without stupid enhancements like this.
