Piaui Apisto (Apistogramma piauiensis) Care Guide
Apistogramma piauiensis 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 piauiensis is a dwarf cichlid of the family Cichlidae, described by Kullander, 1980. It is native to the Parnaiba River basin in Brazil. According to FishBase, it reaches about 2.3 cm in standard length.
Taxonomy
- Family: Cichlidae
- Scientific name: Apistogramma piauiensis
- Describing authority: Kullander, 1980
Habitat
The Parnaiba River basin in Brazil forms the natural range of this species. Like most members of the genus, it favours sheltered margins of streams and creeks with leaf litter and gentle flow. Apistogramma species typically occur in shallow water, often less than 40 cm deep.
Tank requirements
- Minimum tank volume: 80 L (~21 US gal)
- Temperature: 24-28 °C (75-82 °F)
- pH: 5.5-7.2
- GH: 2-10 °dGH
- Adult size: 5-8 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 2018.
Apistogramma piauiensis Breeding Guide
Overview
Apistogramma piauiensis is a small dwarf cichlid from the Parnaiba River basin in northeastern Brazil. FishBase records a maximum length of 2.3 cm SL, making it one of the smallest members of the genus. Like nearly all Apistogramma, it is a substrate-brooding cave spawner with female-led parental care. Species-specific breeding observations are limited, so the guidance below combines the FishBase reproduction note for this species with the well-documented breeding pattern of the genus Apistogramma.
Sexing
Detailed sexual dimorphism for A. piauiensis is not described in available scientific sources. Across the genus Apistogramma, males are generally larger with more extended, pointed unpaired fins, while females are smaller and rounder; this pattern is documented for the genus rather than confirmed for this species specifically.
Conditioning
Apistogramma are carnivorous micropredators. FishBase lists a trophic level of about 3.1 for A. piauiensis. Conditioning a harem on small live and frozen invertebrate foods supports egg production; the species occupies soft, warm freshwater in nature.
Breeding Setup
- Temperature: 20-29 °C (FishBase range for the species)
- pH: 5.5-6.5 (FishBase)
- dH: 2-10 (FishBase)
- Spawning sites: enclosed caves; female deposits eggs on the cave ceiling
- Layout: sand substrate with stones/wood forming small caves (genus pattern)
Spawning Behavior & Trigger
FishBase records that eggs are deposited on the ceiling of caves with the female providing care. For the genus, Wikipedia notes that nearly all Apistogramma spawn in crevices or small caves, in holes in sunken wood or among leaf litter, and that most species follow a polygamous harem strategy in which one male holds a territory containing several females. Soft, warm, acidic water typical of the natural habitat supports spawning.
Egg & Fry Care
The female tends the eggs and larvae inside the cave while the male defends the surrounding territory from predators, a division of care documented for the genus. After the larvae become free-swimming the female leads and guards the fry. For the genus, warmer water tends to produce more males, and in some species more acidic (lower pH) water also skews the sex ratio toward males; this is documented for the genus Apistogramma, with species-specific data for A. piauiensis limited.
Common Challenges
Because data for this species is limited and it is very small, maintaining stable soft, warm water and providing secure caves are the main practical concerns. Conservation status is Data Deficient (IUCN, assessed 2018), reflecting how little field information exists.
