Lake Tanganyika 33 gallon stocking help

[Bomby587]

I have a 33g tank
80x40x40-45 can't remember

It has 6 inches of sand and a pH of 8.2


Stocking

4x masked Julie's
6x n.brevis
Or would multifatinatus be a better species to go with?

Will brevis create a colony like multies do ?

Any more suggestions?
