Use a dark substrate and provide hiding
places with wood and roots.
Cover the tank well.
Water chemistry: pH 5.5-7 (6.0), 4-14 dH (8), 68-73°F (20-23°C).

L)

The eggs adhere to the tank bottom.
Remove
the eggs after a day's spawning.
The eggs take 10-14 days to hatch and the fry can be raised on small Brine Shrimp nauplii.
