Hoplisoma breei — Corantijn Cory

Corantijn Cory

Hoplisoma breei

Rarely exported species from Suriname, very similar in pattern to C. bicolor but smaller. It has a striking bar crossing the eye and a spot at the base of the dorsal fin.

Description de l'espèce

Geographical Origin and Habitat: Suriname: endemic to the Corantijn River basin (Kabalebo River). A very elusive species, it lives in quiet clear-water forest streams, with wooded banks and a bottom full of twigs and natural debris (gallery forest habitat).
Taxonomy and Morphology: Also identified under Lineage codes or C-Numbers before classification. Typical Corydoras shape, blunt and round snout, medium size around 4.5 - 5 cm (1.8-2 inches). Like all true Corydoras it possesses defensive bony plates and powerful spines on the pectoral fins.
Social Behavior: Moderately active species. Due to the highly gregarious temperament, form a robust starting colony (6-10 individuals minimum). Without the perception of their peers, they spend entire days terrified, hidden in the dark of the rocks and refusing food.
Coloration and Sexual Dimorphism: Subdued but characteristic livery. Beige/grayish body. The most salient visual trace is a black band mask vertically crossing the eye (similar to C. panda), but followed by small, very fine black spots along the base of the caudal peduncle and on the dorsal. Females always taller and more robust in the belly.

Soins, reproduction et cohabitation

Aquarium Setup: Typical Suriname biotope setup: construction sand (siliceous and edgeless), knotty roots, and branches inserted like mangroves. Lighting must not blind them; use of lush floaters (Limnobium laevigatum) recommended. Moderate filtration without a "torrent effect".
Diet and Feeding: Carnivorous grazer. Although they clean the bottom of discarded food, they are not satisfied with vegetable feed. Sinking tablets rich in Krill and fish flesh, thawed bloodworms (1-2 times a week). The use of live microworms triggers feeding hyperactivity.
Water Quality: Classic temperatures 22-26°C (72-79°F). Soft to moderately soft waters (GH 2-12). Preferable slightly acidic pH 6.0-6.8. They demand mature water rich in humic acids but very poor in nitrogenous pollutants: a balanced system prevents sudden mortality.
Compatibility and Cohabitation: Impeccable member of peaceful community tanks. Excellent companions are small pencilfish (Nannostomus), hatchetfish (Carnegiella), and Tetras native to Guyana. Highly unrecommended in the presence of aggressive loaches or freshwater pufferfish.
Aquarium Breeding: Very similar to C. panda. Commercial attempts are rare. Pushed to reproduce by "fake rain" cycles with cold RO water mimicking the monsoon. The clear, viscous eggs are scattered singly or in small batches on Anubias leaves. Isolation necessary for rescuing the fry.
Risks and Diseases: Loss of tactile whiskers (on gravel), bacterial infections (Columnaris or Aeromonas) due to poor bottom hygiene. Extreme vulnerability and lethality induced by the administration of Copper doses during Velvet/Ich treatments performed on other host fish.

Profil de poisson

Tempérament
Semi-aggressive
Hoplisoma breei are peaceful, social schooling fish that thrive when kept in groups. Keeping them in numbers of at least six individuals greatly reduces their stress and promotes natural behaviors. They are completely harmless to plants and other tank inhabitants.
Régime alimentaire
Omnivore
These are omnivorous bottom feeders that require a varied diet to thrive. Their meals should include high-quality sinking pellets, wafers, and live or frozen foods like bloodworms. A balanced diet ensures proper growth and vibrant coloration for Hoplisoma breei.
Espérance de vie
5-8 years
Taille adulte
5 cm
Ratio des sexes
Specific M:F ratio
Maintaining a ratio of two or three males for every female is ideal for breeding purposes. This ratio encourages natural spawning behaviors and increases the chances of successful fertilization. In non-breeding community tanks, the exact ratio for Hoplisoma breei is less critical.
Fréquence d'alimentation
Twice daily
They should be fed small amounts once or twice a day. It is important to provide only what Hoplisoma breei can consume within a few minutes to prevent water fouling. Occasional fasting days can also be beneficial for their digestive health.
Charge biologique
Low
The Hoplisoma breei has a relatively low bioload compared to many other species of similar size. They are efficient scavengers that help keep the substrate clean, which slightly offsets their waste production. However, adequate biological and mechanical filtration is still necessary to maintain optimal water quality in the aquarium.
Courant
Stagnant
They prefer moderate water movement that simulates their natural riverine habitats. A gentle current provides necessary oxygenation without exhausting the fish. Avoid overly strong flow that could sweep Hoplisoma breei away or cause stress.
Risque de saut
No
Reproduction
Oviparous
Breeding Hoplisoma breei in captivity is possible but requires specific water conditions and conditioning. They are egg layers that typically deposit their adhesive eggs on broad leaves or the aquarium glass. Parents may eat the eggs, so it is often best to raise the fry in a separate tank.
Compatibilité et compagnons
Community
They are incredibly peaceful and make excellent additions to community aquariums. Hoplisoma breei gets along well with most other peaceful, similarly sized fish. Aggressive or large tank mates should be avoided as they may intimidate or harm them.
Niveau dans le bac
Bottom
They are obligate bottom dwellers that spend the majority of their time on the substrate. Hoplisoma breei constantly rummage through sand or smooth gravel in search of food. Very rarely will they be seen swimming in the middle or upper levels of the water column.
