Which is a better choice for 6ft 135 Gallon Tank

[Pseudotropheus]

Hello,

I have ordered the following fish and would like to know if anyone has any experience with them and if I would be better off keeping the Multis or the Brevis with the Caudopunctatus.

Qty 6 Caudopunctatus small

Qty 6 Brevis Small

Qty 4 Multi Small

The other fish (Multi or Brevis) will go into a 30 gallon long tank by themselves.

Thanks in advance for any advice.
