I am starting up a new 75 gallon tank. I am two weeks into a fishless cycle and I have been researching ideas for stocking. My goal is for an all male tank with shades of yellow and blue. I was also looking for something red, but I was not sure what would work. I do not know know a lot regarding matching realistic tank mates. Would these fish be compatible? 1)Metriaclima elongatus usisya 2) Metriaclima Membe Deep 3) Tropheus sp Red Cheek 4)Labidochromis Cearuleus. I would appreciate any suggestions. Thank you!
