Danio malabar breeding
A week before spawning, two males and one female are separated and kept separately. At this time, they should be fed abundantly. At the same time with the seeding of producers should be poured into the spawning tank fresh tap water. It should stand for about seven days. As a spawning tank is better to use a vessel of 50 to 100 liters. Since the female lays up to two thousand eggs. Such a number of fry will be easier to keep in a large aquarium.
After the water is drained on the bottom of the spawning ground laid or separator net or densely covered with small-leaved plants pressing them clean washed stones. Temperature 25 -28 ° C. Hardness up to 10 °dH. pH – 7. Be sure to provide several points of aeration. Eggs and fry are very demanding to the oxygen content.
In the prepared spawning ground in the evening put two males and one female. In the morning, when the spawning ground is illuminated by sunlight. The males will chase the female. Which will throw eggs. In a few hours she will lay up to two thousand eggs.
If the race did not occur in the first day. Producers can be kept in the spawning tank for another day, feeding them abundantly. After the completion of spawning producers must be removed, so that they do not eat the eggs. Stones pressing the grass to the bottom can be removed. Plants will float and eggs will remain on the bottom.
Half of the water should be replaced with fresh water of the same composition and temperature. It is desirable to add disinfectants to the water. Methylene blue to a pale blue shade or Rivanol at the rate of 1.5 mg per 1 liter.
Incubation lasts up to three days. Then larvae appear, which are attached to the glass with the help of secretion secreted by skin glands. After about 5 -7 days, the fry swim. Starter lump for them infusoria and nauplii crustaceans. As they grow, they are transferred to larger feed and planted in different containers to avoid overpopulation.
It is interesting to observe the strictly expressed hierarchy of the flock. In the center of the flock is often the strongest male. He also has the most horizontal position. As you move away from the center of the pack are weaker individuals. They swim at a greater angle to the horizon. The weaker the weaker, the lower the tail is lowered. It is believed that this distinctive behavior is monitored by the pack leader. If the strongest male is removed all members of the pack swim horizontally. Such a hierarchy in aquarium conditions is not always traced.
