I am in the process of designing a permanently divided tank for my breeder kids. I am thinking of either 1 tank that is 10 feet long or 2 tanks that are 5 feet long. I was thinking of 12 inches high and 12 inches wide. There would be a 2-3 inch space in the bottom for the heater and filter intake with the outflow going into a pipe that has drop tubes going into each section. I am looking at 30 separate compartments.. or 15 to a 5 footer. I plan to drill many small holes in the bottom of each section and in the permanent dividers between each section, and paint each divider... But not the bottom... With some aquarium paint so there is less fighting and flaring between neighbors... Anyone have any suggestions or ideas on ways to get this done or maybe to improve on the idea??
