Apistogramma atahualpa is a South American dwarf cichlid; this guide covers its habitat, water parameters, diet, compatibility and breeding.
Compiled by Aquairi from published sources · Published · Updated
Overview
Apistogramma atahualpa is a dwarf cichlid of the family Cichlidae, described by Romer, 1997. It is native to the Nanay River basin within the Amazon system; it occurs in blackwater habitats near Iquitos, Peru. According to FishBase, it reaches about 4.2 cm in standard length. The species name honours Atahualpa, the last Inca emperor.
Taxonomy
- Family: Cichlidae
- Scientific name: Apistogramma atahualpa
- Describing authority: Romer, 1997
Habitat
The Nanay River basin within the Amazon system; it occurs in blackwater habitats near Iquitos, Peru forms the natural range of this species. It inhabits soft, acidic blackwater stained amber by tannins from decaying leaf litter, with little water movement. Apistogramma species typically occur in shallow water, often less than 40 cm deep.
Tank requirements
- Minimum tank volume: 80 L (~21 US gal)
- Temperature: 25-29 °C (77-84 °F)
- pH: 4.5-6.5
- GH: 1-4 °dGH
- Adult size: 5-7 cm
- Lifespan: 3-5 years
Diet
Apistogramma are omnivores that lean toward micropredation, feeding on aquatic insect larvae, small invertebrates and other tiny prey in nature. In the aquarium they take live and frozen foods such as bloodworms, brine shrimp and water fleas, and many specimens also accept prepared foods.
Compatibility
This is a semi-aggressive, bottom-oriented dwarf cichlid. It is best kept with peaceful upper- and mid-water dither fish such as Cardinal Tetra, Rummy-Nose Tetra, Sterbai Corydoras, Hatchetfish. Housing more than one male of the same species, or combining it with angelfish or larger aggressive cichlids, is discouraged because of territorial conflict, particularly during breeding.
Breeding
Apistogramma are cave spawners. Eggs are laid on the ceiling of a cave or sheltered cavity, and the female tends the eggs and fry while the male guards the wider territory. Soft, slightly acidic water supports spawning.
Conservation status
IUCN Red List: Data Deficient (DD), assessed 2014.
Apistogramma atahualpa Breeding Guide
Overview
Apistogramma atahualpa is a small benthopelagic dwarf cichlid recorded from the Nanay River basin within the Amazon system. According to FishBase it is a cave spawner: eggs are attached to the ceiling of caves and the female cares for the eggs and larvae. As across the genus, the female provides maternal care while the male defends a territory.
Sexing
FishBase gives a maximum length of about 4.2 cm SL for males. As is typical for Apistogramma, the species is sexually dimorphic, with males larger and more strongly coloured and breeding females most frequently yellow with blackish markings.
Conditioning
As a small predatory dwarf cichlid, A. atahualpa is conditioned on small live and frozen foods. Stable soft, acidic water and consistent feeding bring females into spawning condition, reproducing the soft waters of the Nanay River basin in which it is recorded according to FishBase.
Breeding Setup
Provide caves with a ceiling on which eggs can be attached, in a soft, acidic blackwater tank that reproduces the species' preferred conditions. The genus generally requires warm, soft and acidic water for successful spawning and egg development.
Spawning Behaviour & Trigger
Spawning takes place inside a cave, where the female attaches the eggs to the ceiling. According to FishBase the female then cares for both eggs and larvae, providing exclusive parental care, while the male defends the surrounding territory.
Egg & Fry Care
The female tends the eggs on the cave ceiling and guards and leads the larvae after hatching. No species-specific egg count is published by the consulted sources, but care follows the maternal pattern documented for the genus.
Common Challenges
As a soft-water species sensitive to water quality, A. atahualpa requires stable, soft and acidic conditions; maintaining them consistently is the main challenge for successful egg development and fry survival. Wikipedia notes that nearly all Apistogramma spawn in crevices, typically in holes in sunken logs or branches or in leaf-litter aggregations, so reproducing such structure in the tank encourages spawning. It also notes that water conditions affect offspring sex ratios, with warmer water and, in some species, lower pH producing more males, so stable, moderate parameters help yield balanced broods.
