Lunar Wrasse? or Saddleback Anthias?

First off i guess is 50g big enough for a lunar wrasse? and i heard that they like to eat snails and other inverts. Has anybody had troubles with that? im more or less just looking for other people's experiences with the two fish ..thinkin about picking one of the two up soon... thanks

 

The 50 is too small for a Lunar wrasse. It will grow to around 8 inches and is a very active fish.

 

A 50 is way too small for one, and anything in the Thalassoma genus is a bad idea in a reef tank. They'll destroy your inverts, and turn anything/everything over in your tank looking for food unless everything is well tied down. In short, Thalassoma is not a practical reef fish, and this one in particular as it can get to 10" and really needs 150gal.

A few words of caution with the saddleback's. They're a bit picky to get them to eat prepared foods, but once they acclimated to such they're supposedly pretty hardy. However, they're still an anthia, which means you'll need to feed them 3 times/day.
