[ARRIVED 12-MAY-2026] Apistogramma Viejita Red Neck (Macmasteri) - Captive Bred - 4-5cm

Description

 SUB ADULTS SOLD

Behold the Apistogramma Viejita Red Neck, a breathtaking dwarf cichlid that brings an explosion of fiery color and captivating behavior to the planted aquarium. Renowned for its stunning crimson-red throat and neck that contrasts dramatically with its shimmering blue and gold flecked body, this fish is a true centerpiece for discerning aquarists. Our specimens are healthy, vibrant, and captive-bred for hardiness and adaptability, ensuring you receive a fish that will thrive in your care.

Key Features & Benefits:

  • Stunning Visual Impact: The intense "Red Neck" is this fish's signature feature, creating a dazzling display of color that is constantly in motion.

  • Captive Bred Advantage: Unlike wild-caught specimens, our Viejitas are acclimated to aquarium life, are less prone to disease, and accept a wider variety of foods.

  • Ideal Size: As a true dwarf cichlid, they are perfect for well-planted aquariums from 60 litres (15+ gallons) and upwards.

  • Fascinating Behavior: Watch their intelligent and curious nature unfold, especially during breeding when their colors intensify and their territorial instincts create a captivating spectacle.

Product Details:

  • Scientific Name: Apistogramma macmasteri (commonly referred to as "Viejita" morph)

  • Common Name: Red Neck Apisto, Viejita Red Neck

  • Origin: Captive Bred (Species originates from Colombia)

  • Temperament: Peaceful but territorial, especially during spawning. Ideal for community tanks with peaceful, mid-to-top dwelling fish.

  • Maximum Size: Approximately 6-8 cm (2.5-3.1 inches)

  • Size Provided: 3-5cm (Juvenile to Sub-Adult) - You will receive healthy, well-started young fish. Their magnificent red coloration will continue to develop and intensify as they mature.

Care Guide:

  • Recommended Tank Size: 60 litres / 15 US gallons minimum for a pair or trio. Larger is always better, especially with multiple females.

  • Water Parameters:

    • Temperature: 24°C - 28°C (75°F - 82°F)

    • pH: 5.5 - 7.0 (Slightly acidic to neutral is ideal)

    • GH: Soft to moderate water is preferred.

  • Diet: Omnivore. Thrives on a varied diet of high-quality micropellets, frozen or live foods like brine shrimp, daphnia, and bloodworms.

  • Habitat Setup: A well-planted aquarium with plenty of hiding spots is essential. Provide caves (clay pots, coconut shells), driftwood, and leaf litter (Catappa leaves) to mimic their natural environment and reduce stress. A dark substrate will make their colors truly pop!

Who is this fish for?

This Apisto is perfect for:

  • The aquarist looking to move beyond common community fish.

  • Planted tank and biotope enthusiasts.

  • Hobbyists fascinated by fish with personality and complex breeding behaviors.

  • Anyone wanting to add a splash of intense, fiery red to their aquascape.

Order with Confidence:

Your live fish order is handled with utmost care. We package all livestock with professional breather bags and insulated boxes, complete with heat or cold packs as needed to ensure a safe journey to your door.

⚠️ Please Note: Color development is highly dependent on diet, water quality, and the fish's mood/status. The spectacular red neck will be most vibrant in dominant, healthy, and well-conditioned males.


FAQ Section (Suggested for the product page below the description):

Q: How many should I keep?
A: Apistogramma are best kept as a pair (1 male, 1 female) or in a harem (1 male with 2-3 females) in a tank of sufficient size with plenty of visual barriers. Males can be territorial with each other.

Q: Are they suitable for a community tank?
A: Yes, with careful selection. Ideal tankmates are peaceful tetras, rasboras, pencilfish, and dwarf Corydoras. Avoid large or aggressive fish.

Q: What is the difference between "Viejita" and "Macmasteri"?
A: "Viejita" is a common name historically given to a specific colorful population of Apistogramma macmasteri. The names are often used interchangeably in the hobby for these brightly colored strains.

    Live Arrival & Ordering FAQ

    Do you offer a live arrival guarantee?

    Yes. All livestock is covered by our Live Arrival Guarantee.

    In the rare event of DOA, please contact us promptly with clear photos of the livestock in the original unopened bag.

    Please review our full DOA and store policies before purchase.

    Can you ship to all states in Australia?

    No. Due to state restrictions, we cannot ship livestock or live plants to WA and TAS.

    What should I check before ordering?

    Before placing an order, make sure:

    • Your tank is fully cycled and stable
    • Your aquarium has enough space for the species
    • Your current livestock are compatible in temperament, size, and requirements
    • Your water parameters, habitat, and temperature suit the species
    • You are not adding too many fish at once
    What should I expect when my fish arrives?

    It is normal for fish, shrimp, or snails to look pale, stressed, or less active after shipping.

    This is temporary. Most livestock will settle and regain colour within a few days.

    How long does it take for fish to settle in?

    Most livestock will take 3–7 days to fully adjust to their new environment.

    Should I feed my fish immediately after arrival?

    No. We recommend waiting 24 hours before feeding to allow them to settle.

    If you already have fish in your tank, feeding them before introducing new arrivals can help reduce stress.

    Why do fish sometimes struggle after being added to a tank?

    In most cases, issues are caused by tank conditions, not shipping.

    • Uncycled or unstable tanks
    • Poor water parameters
    • Overstocking
    • Unsuitable tank mates
    What is Nano Tanks Australia’s main tip for new livestock?

    Most livestock losses happen in immature or unstable tanks, not during shipping.

    If your setup is not fully established, the risk to new arrivals is significantly higher.

    Not sure if this fish is right for your setup?

    If you are unsure whether this species suits your setup, contact us before ordering and we’ll help point you in the right direction.
