He reported that it healed just fine and did not effect the fishes ability to swim or eat, it was later removed.
There has been no one else since who has attempted this to the best of my knowledge and is not a common practice. So there is no need to get all up on arms about this.
I think it's irrelevant whether this was done 'under sedation by a professional piercer'. Why do this at all???? The circumstances under which a fish was pierced does not justify doing it at all.
20/20 had an episode not long ago featuring people's desire to 'transform' their pets with piercings, tattoos, facelifts, testicle implants, etc. This is actually becoming a lot more widespread than you may realize. New York has impending legislation banning these practices because it's become such a widespread problem.
