Bleekeri with?

[Buphy]

So I recently got a Bleekeri (yes I know there are apparently a ton of names for them, that's just what the store was calling it). He's about 3-4 in right now and in my 55 gallon with my 2 EBJD and 2 normal JD (yes, as they grow i do have a 125 gallon to move some into). While everything seemed fine at first, everyone had their own space that needed it, when I got home from a weekend trip the bleekeri had all four of my jacks on one side of the tank and he had the other 60% of the tank to himself.

My question is; is this going to be a persisting problem or is there something I can do to alleviate it? A few side facts that could be notable: I feed on the side of the tank where the jacks were force to (maybe the bleekeri didn't like having to leave his territory to feed so he expanded?) and my filter is on the side the jacks were forced to (other side doesn't seem to have much flow).

Any thoughts would be fantastic, thanks in advance.

Any nearly black colored cichlids with iridescent spots will be a competitor for a Paratilapia, especially in a small tank like a 55. So if you'd like to keep the JDs alive, you need to move either them, or the Paratilapia soon.
I was able to keep some mature Paratilapia in a crowded 125 for a while, but there were no other blue spotted fish in it.
The male killed 2 of the females after a while, the 2 were put in a 500 gal where tension still remained high, because if she wasn't ready to spawn, she was mauled.
click to run, video is of them in a 125.

Sorry but the only information I fell is relevant from your post is that any dark fish with iridescence will be seen as competition. No, I have no conserns that the 3.5 in bleekeri will kill my 3-4 in jacks and I have no breeding in the tank. Maybe later on it will be an issue but for now the jacks have decided to stick up from them selves and taken up a new part of the territory and the Bleekeri is seemingly happy with his area. And after hours of watching, the jacks will happily take on and make the Bleekeri back off a fight.
