I just paired two Gold Stripe Maroons. I put the small one in with a slightly larger resident GSM. It got harrased for a few days, each day the harrasment was less aggressive. After about five days the resident female clown started to do herding behavior, trying to get the new clown to host in the anemone. After about 3 days of hovering around the anemone, the new clown hosted and now they are a happy pair!!!
