Im currently in the process of getting my tank set up complete and looking towards the future for when i want to stock. After looking at the cookie cutter tanks in the library i think i've choosen my 2 of the 3 species i want. I would like for you all's opinion on ratio of each and how many total. the 2 types im looking at so far are Pseudotropheus saulosi, Labidochromis caeruleus, and I'm not sure if i want Metriaclima estherae or Pseudotropheus sp. "Acei" for the third. With the first two choices, which 3rd fish would work best with the other two?
