Be mindful that anthias while beautiful and very active love to jump, and are known to be tough to keep long-term in an aquarium. You should also try and keep more females than males to curb aggression and chasing. Most species require a varied diet and frequent daily feedings. Others (such as the purple queen anthias) are essentially impossible to keep in the aquarium long term.
Chromis on the other hand are easy to keep, and now there are some neat ones out there. They are also less expensive - but not nearly as interesting as the anthias however.
I know many an experienced hobbyist who no longer tries to keep schools of anthias. If they were not so beautiful it would make it easier though!
