I googled for interviews with atm and the fish tank kings,
Found one of the ATM guys getting interviewed at MACNA, and basically what they said is they made the show for the non-hobbiest, and hinted that they have had actual hobbyist complain about they're show. Then they explained how how a few years ago this was a dying hobby and that they were trying to get new people in and money into the hobby.
Then i found the interview with the fish tank kings, i think its already been mentioned that mrsaltwaterank was interviewing them.
But they talked alot about the new season and how they added more process into the show, also that they set up a large quarantine system.
I think both shows have their own qualities, but one is definitely for the hobbyist and one is more to get people interested.
