Potter's wrasse or angel?

IMO in terms of difficulty it goes Potter's wrasse>Potter's angel>McCoskers wrasse.

Wrasses are good active fish but you have to have a tank ready to house them (matured live rock with plenty of food for it to graze on). Angels always have the risk of eating some corals (zoos, palys, open brains, acans, etc).

My McCosker's doesn't graze on the rock at all, but he's an appetite wrapped in fins whenever I feed the tank. Eats every single thing I throw in there.
