I have a 72gal corner reef with 2 clowns, 1 psuedo, 1 pink spot goby, and 1 coral beauty. My parents are moving and I will be selling their tank, but they have two nice size (2") clowns that I don't want to get rid of. What do you think if I were to add them to my tank. I don't my bio load out of whack, but will they be O.K. with the other two? What are your guy's opinions?
