Apistogramma norbertiApistogramma norberti is a beautiful and relatively rare species from the Madre de Dios drainage of Peru and Bolivia. Males display a vivid combination of blue iridescent facial markings, yellow body tones, and bold dark lateral markings — a color scheme that is distinctive even among the richly colored Apistogramma genus. Named for aquarist Norbert Bayer.Feeding & Care Tip: Always soak Hikari Micro Pellets in a small cup of tank water for 30–60 seconds before feeding — Apistogrammas can be prone to bloat from dry foods expanding in the gut. Hikari Vibra Bites are an excellent treat option; the sinking worm-like shape triggers the natural hunting instinct of these micro-predators and they will snap them up eagerly. Color is most vivid in soft, slightly acidic water with tannin additions. Indian almond leaves and driftwood are highly recommended. For breeding conditioning, Hikari Frozen or Freeze-Dried Tubifex Worms fed 2–3 times per week reliably trigger spawning behavior and improve egg quality.Native to the Madre de Dios River system across southeastern Peru and northwestern Bolivia — a major Amazon tributary draining a biologically diverse region. This species inhabits soft, slightly acidic forest streams with leaf litter and dense overhanging vegetation.Keep one male with two or more females. Males are moderately territorial but peaceful with unrelated species. The blue facial iridescence intensifies dramatically during display — particularly striking in males competing for female attention.Apistogrammas are cave-spawning dwarf cichlids. The female takes on all parental duties — she guards the eggs and fry aggressively while her body turns bright canary yellow as a warning signal. Males should be watched during this period as females may attack them to protect the spawn; providing sight-breaks with plants and décor helps reduce tension. Coconut caves, clay pots, or driftwood crevices all make excellent spawning sites. Fry are initially tiny and require infusoria or freshly hatched baby brine shrimp for their first meals. Apistogrammas are found in the leaf-litter zones of blackwater forest streams and require a well-decorated aquarium to feel secure and display their best color. A dark substrate, driftwood, leaf litter (Indian almond leaves are ideal), and dense planting around the edges with open sandy areas in the center replicates the natural habitat and dramatically reduces stress. Stressed apistos hide, fade in color, and become susceptible to disease. A comfortable apisto is a spectacular one.Care & Ideal Parameters Difficulty Moderate Temperament Peaceful — Dwarf Cichlid Community Male Adult Size 3.0 inches (7.5 cm) Female Adult Size 1.75 inches (4.5 cm) Min.
