What would you do if you were me?

I've been thinking and thinking about where I want to put my fish, but I can't figure out what I want to do. I'm trying to consolidate my fish and make better use of the space. I have a 300 wide that isn't going to change and I know my larger bichirs and gar are going to go into the 125 and out of the 210 long. I will list my tanks and my fish.

tanks:
210 long (7x2x2)
75 gallon
40 breeder (might try to break down)
20 long (hoping to break this one down for sure)

fish:
4" male motaguense
4.5" female motaguens
- those are currently divided in the 20 as they fight, but I'm hoping if I put them in a larger tank, they will be okay together. I might get a small oscar to help distract their aggression and maybe some target fish.
- the following are in the 125 right now:
4.5" female festae
5" cichla kelberi minas cereas
6" cichla kelberi minas gerias
7 bichirs @ 6-11"
4.5" raphael catfish
- the following are in the 75:
2 6" tigrinus catfish
11" BGK
- this one is in the 40:
4" female hystrix

I am also getting 3 4-5" GATF in a few days.


the kelberi I'd like to maybe keep by themselves or with limited tankmates to get them a little bigger so they can go in w/ the rest of the bass in the 300.


thanks
