SO I have been cycling my new tank and am gradually adding small pieces of coral and hardy fish, etc. In my old 13.5 gallon (everything is going into 72 gallon) I have clean up crew, cleaner shrimp and a large (3 inch) clown as well as a fairly big royal gramma. Both very possessive of their areas, but get along fine. I have cycled my new tank with sailfin mollies and pj cardinals. Going to add a couple wrasses, (probably carpenter's and six line) maybe a coral beauty angel then possible a bristle tooth tang. What is the likelihood that the clown and gramma will "loosen up" their attitudes and possessiveness of the tank when put in the larger tank? Do you think it very necessary to aid in this by adding the wrasses before them? Please let me know your thoughts and thank you in advance!
