It could be a problem, but I'll try anyways. Established fish in an aquarium will always dominate over new comers. To avoid this practice and to give every new fish a chance, I plan on removing all the fish and restructuring the entire aquascape. This give everyone an equal chance to develpe new territories. This method has worked for me many times with killer cichlids, hopefully this will prevail for marine as well.
