I am thinking of different ideas for stocking a 75-90 gallon tank. I want to have groups of 1m 4f of Afra Jalo Reef's, Rustys, and Fuelleborni for sure. I was wondering if it would be ok to mix in some single males in there such a 1 Polit, 1 Chewere (not sure with Jalo Reef?), and 1 Yellow Tail Acei?
