They are fairly hardy. If you can keep a BTA alive, I'd think these will do fine for you. They don't tend to wander, usually take hold in the rock or substrate and stay there. They will require feeding meaty foods. Be sure to show us some photos if you get one or two. $80 seems pricey unless it's a rare color morph which those don't sound to be. You can usually get them at frag swaps, reef shows, or online for $10 for the common ones. Liveaquaria sells them for $9.99.
