My brother inlaw and mother inlaw went halves on it and picked it up for me. Currently I have two female festea, and a a sveni pike in the top tank wich dosent have a devider, the middle tanks have a green terror and two silver dollars on one side, and a rainbow cichlid with 5 swordtails on the other side. The bottom tanks are empty. I don't really know what I'm gonna do with this system in the long run but its probably going to be a breeding settup adventually.
