That sounds beautiful.A monster tank with some light tidal swell flow would be very cool with Achilles tangs. I notably only saw small groups of Achilles usually alone on a group of rocks, whereas I tracked a school of about 200 convicts and orange shoulders (~100 each) traveling together from rock to rock picking away at the algae. Also notable was that each large rock seemed to have its own pygmy angel trying unsuccessfully to defend the rock against the school of tangs. That was entertaining.
