Breeding

Breeding shrimp Macrobahium acanthurus in aquarium conditions presents certain difficulties, primarily because the larval phase occurs in brackish water, in fresh water, the larvae quickly die. If, however, it is possible to create suitable conditions for spawning shrimp, then obtain offspring from them quite possible.

Macrobachium acanthurus is characterized by high fecundity, one female can incubate about 20 000 eggs. Under natural conditions, spawning occurs during the rainy season. The hatched larvae swim for a few hours and then descend to the bottom or to the leaves of plants, and remain there until they have their first molt.

During the first larval phase, the larvae do not feed, consuming nutrients from the yolk sac. They then go through a carnivorous phase, feeding on zooplankton. At this time, under aquarium conditions, the larvae can be fed artemia. Later, you can start giving high-protein foods.
After the larvae have grown a little stronger in the wild, they begin to migrate upstream, and usually by the age of 4 months they reach their main habitat. By this time, the shrimp are sexually mature.

Life expectancy of Macrobrachium acanthurus in aquarium conditions is about 4 - 5 years.
