For this approach is suitable small aquarium of about 30 liters, which should be filled with water from the main tank. At the bottom to place a separator grid and whether to plant bushes of javanese moss.
Producers (1-2 pairs) are planted in the spawning tank and fed abundantly. Spawning takes place in the morning hours. Immediately after spawning producers should be removed.
The eggs are incubated for 50-60 hours. Hatched larvae are sedentary for about 2 days, after which they begin to swim and feed. The starting food for them are micro worms, artemia, powdered dry food.
