There's something about a bad fish, but not about taking away its magic, actually.
I doubt WPM would wait to demote someone when he feels it's needed, especially without consulting the rest of the moderation team.
So I'd have to guess that the fish are not actual people, but in fact groups of people. The bad fish (spammers, rippers, rule-breakers) are bad fish, the good fish (positive contributors, friendly, whatever), well:
Magic is given to those who are accepting of everyone;
Magic is given to those who positively impact the most with what they are birthed.
I think the clue is: "Be good, and you'll be promoted"
And now I've started it
I'm guessing 15 pages (of 50 posts/page) with at least 95% of the posters having no powers but obviously hinting at the fact that they would like for that to be the case.
