A good breeding tank would be around 2 feet long and a minimum of 8 to 9 inches wide and 8 inches deep. In essence a small tank. Rinse it well and make sure it is clean of foreign material. Keep the temperature around 78-80 degrees. Put many well-cleaned plants in the tank.
Long ones are preferable on the extremeties of the tank and short ones in the middle section.
Insert them in the sand so they remain well in place. Plants that clump are excellent. The males and females should be kept apart. When time for a spawning effort comes around choose a female with a U-shaped belly and a real nicely colored male. Place them in the tank you have prepared making sure that no ammonia and or nitrites are present.
