Panda Corydoras

The Panda Corydoras (Corydoras panda) is one of the most popular and recognized armored catfish in the freshwater hobby, named for its charming black and white panda-like patterning. It has a pale, almost white or cream-colored body adorned with three distinctive black markings: a mask covering the eye, a large blotch beneath the dorsal fin, and a band at the base of the caudal fin. This combination creates an immediately recognizable appearance that has made it a perennial favorite among aquarists worldwide. Native to clear, cool streams and tributaries in the Ucayali river system in Peru, the Panda Corydoras inhabits slow to moderately flowing water over sand and fine gravel substrate, typically in shallow, well-oxygenated sections. Like all corydoras, it is a schooling, benthic species that uses its sensitive barbels to sift through the substrate searching for food particles. It breathes atmospheric air periodically by darting to the surface, which is normal and healthy behavior. In the aquarium, Panda Corydoras thrive in groups of six or more and become noticeably more active, confident, and interesting to observe when properly schooled. They are completely peaceful toward all tankmates and spend their time foraging on the substrate, making them excellent companions for mid and upper water fish. They prefer cooler water than many tropical species (18–25°C), which is an important consideration when selecting tankmates.

Tank Setup: A minimum of 60 liters is suitable for a group of six. Use fine sand substrate — the corydoras will sift through it constantly with their barbels, and coarse gravel can damage these sensitive appendages over time. Provide hiding spots with smooth driftwood, rounded stones, and dense planting. Leave open areas of sand for foraging.

Water Parameters: Target pH 6.0–7.5, GH 2–15, KH 1–8, and temperature 18–25°C. The preference for cooler temperatures is notable and limits suitable tankmates to other cool-water or adaptable species. Perform 25–30% water changes weekly. Good oxygenation is important as this species comes from well-aerated streams.

Filtration: Use a reliable hang-on or canister filter providing gentle to moderate flow. Sponge prefilters are useful for protecting the barbels from being sucked against intake tubes. Clean the substrate periodically to remove detritus accumulation.

Feeding: Sinking foods are essential. Offer high-quality sinking pellets, Repashy gels, frozen or live bloodworms, daphnia, brine shrimp, and Tubifex worms. Feed in the evening or with lights dimmed to ensure food reaches the bottom before other fish consume it.

Social Behavior: Keep in groups of at least 6. They school together, forage as a group, and show much bolder behavior in larger numbers. Completely non-aggressive toward all tankmates. Excellent companions for tetras, rasboras, and small livebearers.

Health: Barbel erosion from coarse substrate or poor water quality is the most common health issue. Maintain fine substrate and excellent water quality at all times.
