This is not a troll. This is a foolish and headstrong child who has more will for being right than regard for the life of fish. I say "child" because a mature person would not seek advice from people with considerably more experience and completely ignore it just to be right.
This seems to be a battle between an older brother and a younger one with, unfortunately, fish as the victims. One can only hope that brother the younger will swallow a small amount of pride for the benefit of the fish, and leave the rest of us who are interested in the hobby alone-- but that's what an adult would do. A child would willfully insist on his own way and bother others until he gets it.
