Last week I bought 2 maroon clowns hoping that they would pair up. Both were introduced into the tank at the same time. As soon as they were introduced one seem to be more agressive then the other one. Recently the aggressive one started hosting my BTA and has gotten more aggressive. He won't let the other one get anywhere near the BTA. What are my options? Should I just be patient and let things cool down? It's been about 2 weeks now since I bought them.
