okay i got 2 ocelaris clowns and my original was 1 and a half inches. 5months later i added a 1 inch and i aclimated him. then while doing that i took my old clown and put him in a bucket. after aclimation i took the new clown and put him in the bucket. after 10 minutes i neted them together and left them in the net in the tank hanging from the top for 1minute. then i let them go. twithing started instantly indicating peace and mating.
