I have a 120 gallon tank and i want to finally take the plunge and get a pair of Red Isletas from Rapps but was wondering if I should get 2 females and 1 male, just a pair or just a single male given the tank is only about 50 inches and deeper in width? Maybe this isn't even the best style tank for this particular fish but its the only one I have available. I was all set to just get a nice show male but I do tend to grow tired of a single show fish in a tank and think I would enjoy the fish more it he had a mate or 2. What do you guys think?
