Hoplo Catfish (3-4 CM)

Description

Overview & Taxonomy
  • Scientific Name: Megalechis thoracata (Synonyms include Callichthys thoracatus and Hoplosternum thoracatum)

  • Family: Callichthyidae

  • Common Names: Hoplo Catfish, Spotted Hoplo, Black Marble Hoplo

  • Native Distribution: Widespread across the Amazon, Orinoco, upper Paraguay River basins, the Guianas, Bolivia, Brazil, Colombia, Ecuador, Peru, Suriname, and Venezuela.

Key Characteristics & Size

  • Size: Grows to an average maximum adult size of about 6 inches (15 cm), though some individuals can reach slightly larger.

  • Body Armor: Covered in two rows of overlapping bony scutes (plates) along the flanks and equipped with strong pectoral spines.

  • Air-Breathing: Like other callichthyids, they possess modified intestines that allow them to swallow atmospheric air from the water’s surface, helping them survive in low-oxygen (hypoxic) environments.

  • Behavior: Predominantly nocturnal, peaceful, social, and active bottom-dwellers often compared to giant Corydoras.

Aquarium Care

  • Tank Size: A minimum tank capacity of around 55 gallons (or a 4-foot tank) is recommended, especially since they thrive best when kept in small groups or colonies.

  • Water Parameters:
      • Temperature: 18–28 °C (64–82 °F)
      • pH Level: 6.0–8.0

  • Substrate: Soft sand or fine gravel is essential to protect their sensitive barbels and undersides from scraping.

  • Tank Mates: Peaceful and large enough not to be mistaken for a meal; avoid tiny fish like neon tetras, which nocturnal hoplos may consume.

  • Diet: Omnivorous scavengers that readily accept sinking pellets, wafers, granules, and live or frozen foods.

Reproduction

  • Nesting: Males construct floating bubble nests, often incorporating bits of floating plant matter.

  • Spawning & Care: Spawning is often triggered by cooler water changes. Males aggressively guard the adhesive eggs and resulting fry.
