I'm planning on building a paludarium with a rather large water section. The measurements of the aquatic section will be 68inches long, 24 inches deep and 24 inches high and equate to approximately 165 gallons. A few fish I know I want are around 8 cherry barbs and around 15 cory cats. I'd like to have a schooling fish or two and a nice centerpiece fish but, I'm so indecisive. Any suggestions?
