I haven't had an aquarium for 15 years. I have PLENTY of empty wall space in my house, so I'm getting a 125. I WAS gonna do a planted tank, but I think I'll hold off on that for a while. I want to start with a SA/CA cichlid tank first. I remember having some, really liked watching them. I'm thinking 2 2217 Eheim Canisters would work well for this tank? It will be 72"L x 18.5"W x 23"H.
