Centropyge acanthops --I have a 6 wks old Red Sea max that is running well woith good parametres. Some soft corals and a cuc that are doing well and I have a neon goby in quarantine waiting to go in later. In the future I am looking at adding one or two perculas but would like to know if this little angel would be an angel in a tank like this- I have seen they can be territorial??
