6 is good 12 is better?

Mine love brine shrimp, mysis shrimp, some calerpa and even share the algae sheets on the clips with the tangs.

As mentioned they do better in a mature tank. Seeing them eat in the store would be a good sign. They should have an abundance of live rock to pick from and hide in. They love to swim in and out of the rock and are more out going if they have it near. Unlike some other wrasse,s such as my leopard, they do not bury in the sandbed, but sleep in small hideouts in liverock.

Should also be know, they can at anytime, turn to bullies.
