Aphyocharax nattereri are fairly calm fish, but can molest low-active fish and those with voile tails. When keeping Natterera afiocharaxes in a common aquarium, South American dwarf cichlids and apistograms would work well as neighbors. Keep afioharaks need a group of at least 6 individuals. An aquarium with a volume of 50 liters is suitable for such a number of fish.

The aquarium should be densely planted with aquarium plants, including floating on the water surface, with open areas for free swimming. At the bottom can be placed snags and large stones.

Water parameters: temperature 22-27° C, hardness dH 1-15°, pH 5,5-7,5. Need filtration, aeration and weekly replacement of 1/3 of the aquarium water with fresh. The aquarium should be covered to prevent the fish from jumping out of it.

The substrate can be anything.

Ambient light with an intensity of about 0.3 W / L. Daylight duration of 10-12 hours per day.

The fish are omnivores and eat most dry, frozen and live food. The fish are fed daphnia, artemia, small mosquitoes, dry flakes and pelleted foods. Feed should be given 2 times a day.

Reproduction

For breeding Aphyocharax nattereri requires a small spawning tank, planted with bushes of small-leaved plants, such as Javanese moss. Water should be soft dH 2-5 ° and acidity pH 5,5-6,0.

Before spawning fish strenuously fed a variety of food. When females noticeably rounded abdomen and males acquire a bright color, you need to select from among the largest and transfer them to the spawning aquarium, where they continue to feed intensively.

Spawning takes place in the morning hours. Females chaotically hatch eggs, and males immediately fertilize it. The eggs are deposited on the leaves of plants, but they do not stick to them, and sink to the bottom. Some eggs even float on the water surface.

Once spawning is over, the producers are removed from the spawning tank, as they may eat all of their eggs.

The eggs incubate for 24 hours. Hatch larvae are sedentary for the first couple of days and feed on nutrients contained in their yolk sacs. Gradually the fry become more and more active and begin to swim and feed. The starting food for them are infusoria, and then, as they grow, they begin to be given micro worms and artemia.

The fish are quite prolific and are able to spawn quite often.
