I am surprised at the focus on clownfish rather than tangs. Since the tangs cannot be captive bred, and require much higher conditions for living (bigger tanks, generally less hardy than clowns), I would think the wild tang population would be seeing more reduction than the wild clown population. ESPECIALLY seeing as clowns are so easy to breed in captivity (I can't think the last time I saw one that actually wasn't - though I don't frequent the big box stores). Both of my sets of clowns were captive bred, and my orange ones actually have a whole slew of offspring out in the world (the guy I bought them from estimated he sold well over 100 clowns over the course of a couple years).
I'm also skeptical of a nonprofit raising clowns to sell to the public. They're prices must be very very low if they're going to compete with the for-profits (aforementioned owner of orange clowns said he sold them for about $10 a piece).
