I personally am a big fan of Anthias and I don't think there would be anything more impressive than an Anthias tank. I would put 5-6 females and 1 male in there. I like these fish because they stay out in the open, are fairly hardy, and eat well. The tips I would reccommend for an anthias tank are similar to tangs: super-high O2 content (via skimmer or wet/dry, skimmer preferable) and constant feeding. These fish are plantivores and in the wild eat nearly constantly. Feed them at least 4 times a day mostly meaty foods like shrimp, clam, mysids, brine shrimp, and even live ghost shrimp on occasion. Also, when you stock them, put them all in at once (make sure the tanks bio filter can handle this!!) and add only 1 male to a tank and several females. Another thing they need is many "bolt-holes" where they can hide if they feel threatend for some reason.
