Hoplisoma weitzmani, now more commonly known as Corydoras weitzmani, is a species of Corydoras catfish. This species is named in honor of the ichthyologist Stanley H. Weitzman. Corydoras weitzmani is known for its striking coloration and unique markings. Here’s an overview of Corydoras weitzmani:

Appearance

• Coloration: Corydoras weitzmani is easily recognizable due to its distinctive black and white coloration. It typically has a pale body with a prominent black band running diagonally from the base of the dorsal fin to the lower body. There is also a notable dark blotch on the dorsal fin, giving it a striking contrast.
• Size: They are a relatively small species, growing up to about 1.5 to 2 inches (4 to 5 cm) in length.

Behavior and Temperament

• Temperament: Corydoras weitzmani are peaceful and social, making them ideal for community aquariums. They are non-aggressive and get along well with other small, peaceful fish.
• Social Behavior: Like other Corydoras, they are social fish that thrive in groups. It is recommended to keep them in schools of at least 4-6 individuals to encourage natural schooling behavior and reduce stress.

Tank Requirements

• Tank Size: A minimum of a 15-gallon (60 liters) tank is suitable for a small group, but a larger tank is preferable to provide ample swimming space and stable water conditions.
• Substrate: A soft substrate, such as fine sand or smooth gravel, is ideal for protecting their sensitive barbels while they forage for food along the bottom.
• Water Conditions:
  • Temperature: 72-78°F (22-26°C).
  • pH: Slightly acidic to neutral, around 6.0-7.5.
  • Water Hardness: Soft to moderately hard water (2-12 dGH) is preferred.
• Aquascaping: Provide a tank with plenty of hiding places and shaded areas using plants, driftwood, and rocks. This creates a comfortable environment that mimics their natural habitat and allows them to feel secure.

Diet

• Omnivorous: Corydoras weitzmani are omnivores and will eat a variety of foods. They do well on a diet of high-quality sinking pellets, supplemented with live or frozen foods such as bloodworms, brine shrimp, and daphnia. A varied diet helps to ensure they receive all the necessary nutrients.

Summary

Corydoras weitzmani is a beautiful and unique species of Corydoras that brings both visual appeal and lively behavior to an aquarium. Their peaceful nature and small size make them an excellent choice for community tanks. By keeping them in groups and providing a suitable environment, you can enjoy their natural behaviors and contribute to their well-being.
