When I first saw the list, before I actually read it, I thought it was goign to be a "Ban the capture of the following fish" list. This of course would annoy me. Saltwaterfish.com has (or at least had) a blurb on their site saying they will refuse to sell more than one large angel to anyone, because you should never have more than one in a tank. This may be a "good idea" in general for newbies or people with small tanks, but there are plenty of larger tanks out there with multiple large angels doing just fine.
But I digress...Peter's list, now that I've actually read it, seems to be more of an informative list since plenty of the people who SHOULD know better (e.g. LFS employees) apparently do not. An LFS near me which frequently has batfish for sale

recently had a shipment of Ornate butterflyfish. Right now, with what we know today, I don't believe any of those fish had a chance in hell of surviving. Now, do I think all those people who bought them wanted to keep them for a couple weeks and were OK with them perishing soon after? No, I'm sure most just had no idea, and would have avoided the purchase had they known. The LFS should have known not to order them, the collector should have known not to collect them, etc. That said, maybe some day research will come up with a prepared food that is a good substitute for coral polyps and we can all keep them fat and happy. However, there are a few people qualified to do that kind of research, and about a million times more who aren't. The first group has a real chance to advance the hobby. The second group is just going to kill a lot of fish. I don't really see it as a "fish rights" thing...but nobody benefits from that result.
OK, enough rambling, but any resource that informs people is a good resource, so...nice list.
