Duplicareus Cory (Hoplisoma duplicareum) – Orange-Headed Corydoras

The Duplicareus Cory, Hoplisoma duplicareum (formerly Corydoras duplicareus), is a peaceful bottom-dwelling catfish from Brazil’s upper Rio Negro basin. Its pale body, black eye mask, broad dark back marking and orange-gold patch behind the head make it a distinctive addition to a group of corys. These fish are offered in Large size and are sold individually.

Duplicareus Cory Key Features

  • Distinctive Markings: A dark eye mask and broad black dorsal band contrast with a light body.

  • Orange-Gold Head: A warm orange patch behind the head adds a striking splash of color.

  • Peaceful Temperament: A social bottom dweller for a calm community of suitably sized fish.

  • Group Living: Keep a group of at least six, with more space for a larger shoal.

  • Active Forager: Sensitive barbels help this cory search the substrate for food.

Duplicareus Cory Care Requirements

  • Tank Size: A 20-gallon or larger aquarium for a group, with open floor space, fine sand and shaded places among wood or plants. Keep the substrate clean.

  • Water Temperature: 72–79°F (22–26°C). Maintain stable water quality and good oxygenation.

  • pH Range: Approximately 6.0–7.5. Avoid sudden changes in water chemistry.

  • Diet: Omnivorous. Offer sinking catfish pellets or tablets, supplemented with suitable frozen or live foods such as daphnia or brine shrimp. Do not rely on leftovers.

  • Tank Mates: Peaceful tetras and other small, non-aggressive fish with similar water requirements. Avoid large predators and fin-nipping tankmates.

Shipping & Care FAQ

Common questions about ordering, shipping, acclimation, and care. Have a different question? Contact us.

How long does fish shipping take?
All orders ship overnight via FedEx or UPS from our Philadelphia, PA facility. Most US addresses receive their fish within 16-24 hours of dispatch. We ship Monday through Wednesday to ensure fish arrive before weekend transit holds.
What is the Live Arrival Guarantee?
Every overnight shipment from Amazonia Tropical Fish LLC is covered by our 100% Live Arrival Guarantee. If a fish arrives DOA, we provide store credit — photo documentation within 2 hours of delivery is required.
How do I acclimate fish from Amazoniafish.com to my aquarium?
Float the unopened bag in your aquarium for 15-20 minutes to equalize temperature. Then drip acclimate over 45-60 minutes using airline tubing (1-2 drops per second) into a holding container. Net the fish into your tank without adding bag water. Dim lights for the first 24 hours.
How are the fish packaged for overnight shipping?
Fish ship in oxygenated double-bagged plastic bags inside insulated styrofoam boxes with heat or cool packs depending on season. Fishes are bagged with proper water-to-fish ratio. Boxes are clearly marked LIVE FISH on all sides.
Are the fish quarantined before shipping?
All wild-caught and imported fish undergo a multi-week quarantine at our facility. Specimens are prophylactically treated for internal and external parasites and verified to be eating well before being offered for sale. Domestic strains are quarantined for at least 1 week.
What if a fish arrives dead (DOA)?
Take clear photos of the deceased fish in the unopened bag within 2 hours of delivery and email us. We process Live Arrival Guarantee claims same-day — store credit is refunded to your account.
Do you ship to Hawaii, Alaska, Puerto Rico, or internationally?
We ship throughout the continental United States plus Alaska, Hawaii, and Puerto Rico. International destinations are not supported due to live fish import regulations and shipping risks. We comply with Lacey Act and CITES regulations for all sales.
What water parameters should I prepare for my new fish?
Most South American tropical fish (angelfish, discus, apistogramma, tetras, corydoras) thrive in soft, slightly acidic water: pH 6.0-7.0, temperature 78-82°F. Specific parameters are listed in each product description. Wild-caught species benefit from blackwater botanicals (Indian Almond leaves, alder cones).
Do you offer wholesale or bulk pricing?
Yes — wholesale pricing is available for licensed retailers. Visit our wholesale page for details and bulk pricing on premium tropical fish.
