Fish ID

I saw these blue things with yellow tails and dorsal fins on the moorish idol thread:

and I have no idea what they are. Any ideas?

Amazing how after so long in the hobby I still find a fish I've never seen in the trade (I think I have seen these in public aquariums). Cool fish, possibly good for my tank, but might eat things I want.

Caesio sp., probably C. xanthonota. Their eventual size and activity level makes them completely unsuitable for a tank that size. Might as well put 3 Naso vlamingi in there too.

Just noticed someone posted my tank is too small to keep these, but no tank size was posted! The article says "A single individual, the best option for most hobbyists, kept with small and peaceful tankmates will do well in a 4’ or longer aquarium", so my 270 is large enough, unless the poster disagreed with the article.

They are too small for hobbyist tanks. They are skittish and quick. Judging by the other fish in that pic, they aren't close to full grown. Even in multi-thousand gallon tanks, they only seem to do well in tanks where they can roam above the rocks or far from them, in the shallower tanks (similar to any hobbyist tank) they often get eye injuries from hitting stuff when darting around.

So 2 different recommendations on tank size. 1 says a 4' tank is fine, and another says multi-thousand gallon tanks are too small.

Sure you can keep a small one in a 4' tank but the problem is that they can grow to over 14" long. Too big for anything less than a huge tank.

The article is wrong. Written by someone who I seriously doubt has ever kept a full grown individual in captivity.
