The bleheri might be a pair. They may just be settling in and since the fire and ice was a diffrent species it was targeted first . Also worth mentioning any stress like improper setup or acclimation in a new home also can delay the fighting .
It's only once they are settled in and they start to mature that they show their true colors . Unfortunately only time will tell if your bleheri are a pair however in my experience the best odds of pairing is done from a group , the competition between them seems important for the bonding to occur.
As for the pulchra , same scenario. Sorry I cannot sex them from that video . They could be a pair , they could also just be siblings who have been raised together, eaten their way through their siblings but haven't matured enough to turn on eachother or are under some sort of stress that's delaying them from acting normal and fighting it out (like being stuck in a tiny little bare tank )
As mentioned above It's never a sure thing with channa they could look to be getting along then one day the dominate fish decides it's no longer sharing it's space and everyone else dies. Even bonded pairs can turn on eachother. Although typicall if they pair and are kept properly they will remain peaceful but it's not always the case.
Hope that helps, it's not all good news but that just part of dealing with channa!
