I am not a clown expert, but let me quote from Joyce Wilkerson's Clownfishes page 137:
"Because social surroundings determine gender, clownfishes from the
Amphiprion genus can form a pair from any two juveniles. Two well-cared-for small Amphirprion clownfishes can be become a male/female pair, or a large clownfish (presumably already female) and a smaller one (adolescent or male) can also form a pair. Avoid pairing two large clownfishes, because they are probably both female and each will attempt to cahese the other out of its territory. Two confined females may duel to the death."
DragonFish - it sounds like you have 2 females in your tank. While I can't be 100% sure on that, I think you may want to consider removing one of the females.
