Aquarium: A tank measuring 20" (51 cm) with a capacity of 10 gallons (38 L) is sufficient.   Follow suggestions for A. gardneri .
Water chemistry: pH 5.5-7.5 (6.5), 2-10 dH (4), 70-73°F (21-23°C)
Social behavior: A lively, peaceful species that should be kept in pairs or one male with two females.

Breeding techniques: Use water with a pH from 5.5-6.0, a water hardness from 2-5 dH, and a temperature from 73-77°F (23-25°C).  Plant the tank heavily with fine-leafed plants.   Use subdued lighting and a peat substrate.   The eggs are laid on or sometimes in the peat substrate.  Remove the peat three to four weeks after the spawning and store it in a dark, moist area with a temperature in the upper 70's for 6-9 weeks.   After this time, place the eggs in a tank with soft water (1-5 dH).  Start feeding the fry with roftiers and Infusoria.   
Breeding potential: 7.  Breeding is moderately difficult.
Remarks: This species is an annual, and as a result, is relatively short-lived.   Several color/geographical races are known.  Sexually mature at four months.
