I have two Ocellaris clowns in my tank. Both about 2 to 2 1/2 inches long. Equal in size. I put them both into the tank when they were about 3/4 to 1 inch long, about two years ago. I expected one to stay smaller than the other with the larger clown being the dominant female. However, they both grew equal in size and do not really exhibit mating behavior, but are not aggressive towards one another. My question is did the mating not happen? And if not, do you think I have two males or two females?. Any thoughts from experienced reefers would be greatly appreciated. Thanks.
