Good fit for your tank?

Good fit for

  • Mature planted aquarium setups
  • Advanced shrimp keepers
  • Peaceful nano aquariums

Think carefully if

  • The aquarium contains shrimp-eating fish
  • The tank is newly cycled
  • Water conditions change frequently

A small Peruvian blackwater Apistogramma recognised by its black chin marking and tall anterior dorsal fin. It needs warm, very soft acidic water and a cave-rich aquarium.

Appearance and Identification

A compact Apistogramma with a conspicuous black chin or throat area, a dark lateral band, and extended anterior dorsal membranes in adult males. Males may show blue, yellow, orange, and red accents, while breeding females turn yellow with strong black markings.

The persistent black chin patch helps separate this species from similar cacatuoides-complex fish. Confirm the separation of the lateral band from the caudal-peduncle spot and do not confuse commercial A. juruensis labels with A. allpahuayo.

Males are larger and develop longer anterior dorsal membranes, more fin extension, and stronger colour. Females are smaller and show yellow-and-black brood colour during spawning and fry care.

Use a mature aquarium with fine sand, abundant leaf litter, wood, roots, dim areas, and multiple tight caves. One male with two females requires more floor space and distinct territories. Gentle filtration and low disturbance are important.

Behaviour and Tankmates

A territorial cave-oriented dwarf cichlid that spends most of its time near leaf litter, wood, and the substrate.

Often kept as one male with one or more females where each female has an independent cave territory. A pair is safer in a smaller aquarium.

Brooding females defend the cave and fry forcefully. Males may harass unreceptive females, so dense visual barriers and escape routes are essential.

Use small peaceful upper-water dithers only in a spacious display. Avoid other dwarf cichlids, intrusive bottom dwellers, aggressive fish, and ornamental shrimp. A species-focused breeding aquarium gives the highest fry survival.

Stability importance
Critical

Wild habitats are warm, acidic, and low in dissolved minerals. Long-term care and breeding are most reliable in very soft water near pH 5 to 6, with lower values possible in carefully maintained blackwater systems.

Parameter caveat
Very soft acidic water has little buffering capacity. Prepare low-mineral water before adding botanicals or peat, and monitor pH, conductivity, ammonia, and nitrite closely.

Feeding

Diet types
Carnivore, Insectivore
Feeding frequency
Daily
Preferred foods
  • Live baby brine shrimpA useful conditioning food for adults and a staple for juveniles; rinse before feeding.
  • Live or frozen daphnia and cyclopsSmall crustacean prey encourages natural hunting and is suitable for regular rotation.
  • Frozen brine shrimp or mysisOffer thawed portions small enough for the fish to swallow cleanly.
  • Small carnivore micro-pelletUse as part of a varied diet after the fish accepts prepared food.

A small-invertebrate predator that should receive varied live, frozen, and high-quality prepared foods.

Feed small portions once or twice daily. Newly imported fish may need live or frozen foods before accepting pellets. Avoid a long-term single-food diet.

Baby foods
  • Newly hatched brine shrimpPrimary food once fry become free-swimming; feed small rinsed portions several times daily.
  • MicrowormsUseful supplementary first food for fry feeding close to the substrate.
  • Paramecium or cultured infusoriaUseful during the first days for fry that cannot yet take baby brine shrimp.
  • Fine powdered fry foodUse sparingly as a supplement and remove uneaten material.

A cave-spawning maternal brood-care species. The female lays adhesive eggs inside a narrow cave and guards the eggs, larvae, and free-swimming fry. Soft, acidic, low-conductivity water and live foods are important for reliable breeding.
