I have a c.b. Regal angel (5" now, grown from 2"), a 3" female Bellus, a harem of Flame angels (3.5" Christmas Island male and 3, 2.5" females), a 4" juvenile Queen angel (almost at full adult coloration), and a 4" juvenile French angel in my 360 gallon reef tank (600 gallons total water volume including a heavily macro algae and live rock stocked 175 gallon refugium and 75 gallon sump). The reef consists of several large anemones of various species, many various softies (sinularia, nepthea, sarcophyton, zoanthid, a few species of Xenia and other polys) and a large blue Maxima clam. So far, there has been nothing more than the occasional polyp nip on some of the larger sinularia. The fish are thriving on various flakes, pellets, Nori, and occasionally frozen mysis, brine, ect.). I feed 3 to 6 times per day.
I'm enjoying this reef very much and the angels are truly the gems! However, I am fully aware that at any time, any of the angels could develop a more aggressive taste for the corals or the clam. I am willing to sacrifice the corals and will remove the clam should that happen, as these beautiful fish are by far my priority. I consider myself very lucky to have such beautiful and healthy angels.
