My gentle male frontosa was being chased around the tank earlier by Princess (terror of the tank). I think she/he is a T-bar. Anyway, Monty the fronty suddenly turned to face her open mouthed and approached her fast. She backed off then came forward again and this went on for a few minutes, then Monty opened his (rather large) mouth again and took the whole of Princess's face in his. This was repeated another 3 times, luckily no injury inflicted. 
Any cich experts out there who can tell me if this is mega aggression or mating behaviour. They've both been ok since.
