I currently have a 55 gallon, 48x13x20 with two Jack Dempsey, one green terror, two convicts, one jewel cichlid. three africans, one texas cichlid. They are all about the same size 1.5 inches. I am looking to purchase a larger tank to move some of them. I was looking at a 120 gallon long 60x18x26, or a 120 gallon high, 48x24x24. What would be a better tank for my cichlids? Longer or higher? Price is about the same! :help:
