Well if u like, the saddleback pair and the true percs are together in a 10 gallon tank with no problems. I wouldn't mix the tomato pair and perc since the tomato female is pretty aggressive. I can do $50 for the saddleback pair, the true perc, and both dottybacks. If u haven't found a seios pump I have an 820 u can have for $30. I think I have all the parts except I am missing one of the suction cups.
