Good fit for your tank?

Good fit for

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

Think carefully if

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

An adaptable western Amazon Apistogramma found across blackwater, clearwater, and whitewater systems. Males show blue facial iridescence, while females become yellow and highly territorial during brood care.

Appearance and Identification

A moderately robust Apistogramma with metallic blue cheek and opercular markings, a dark lateral band, and variable orange, yellow, red, or blue fin colour in males. Females are smaller and turn yellow with black brood markings.

The blue cheek area is useful but not unique. Confirm the lateral pattern, caudal spot, fin shape, body proportions, and provenance because the eunotus complex includes similar forms and historically confused populations.

Males are larger and more colourful, with longer fins and blue facial iridescence. Females are smaller with shorter fins and develop bright yellow breeding colour with dark markings.

A compatible pair can use a 60 cm aquarium. A trio needs more floor area, multiple caves, and visual barriers. Fine sand, leaf litter, wood, and plants create suitable lower-level territories.

Behaviour and Tankmates

A generally manageable territorial dwarf cichlid that becomes much more assertive during spawning and fry care.

Keep as a pair or one male with several females where the layout provides independent caves and escape routes.

Males patrol a larger area, while a brooding female aggressively defends the cave and fry. Bottom-dwelling tank mates are most likely to be attacked.

Small peaceful tetras, pencilfish, and hatchetfish can work in a sufficiently large aquarium. Avoid aggressive cichlids, other Apistogramma in confined tanks, crowded bottom dwellers, and ornamental shrimp.

Stability importance
Important

The species occurs in several Amazonian water types and is comparatively adaptable. Wild or locality-specific fish should still be maintained close to their source conditions. Soft to moderately hard water is generally suitable.

Parameter caveat
Broad tolerance does not mean rapid changes are safe. Acclimate slowly and avoid repeated swings between acidic soft water and mineral-rich alkaline water.

Feeding

Diet types
Carnivore, Insectivore, Omnivore
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 spawner with maternal brood care. The female attaches eggs to a cave ceiling, tends eggs and larvae, and leads the free-swimming fry. Captive breeding is possible across a moderate parameter range, though soft slightly acidic water is preferred.
