typical clown behavior its prob a little everything ...the new bta, similar color and size, territory clowns tend to terorize the weak and the flame is showing weakness so its a target you can try to re arrange some rock work but its a in sight thing if the clown can see it and it doesnt want it around it will push,attack or chase it away.you can add some hiding places with pvc piping untill the clowns are a little more use to it but eventually they will either work it out or the weaker of the two will get stressed and die or be killed.........what can i say clowns are aggresive fish
