📍 South America

A corydoras from the Huallaga and Ucayali rivers in Peru featuring a pale body with a distinctive dark lateral stripe and subtle secondary spotting. Peaceful and social, it thrives in groups of 6 or more on fine sandy substrate with soft, slightly acidic to neutral, well-oxygenated water.

Care Guide

Diet

Zygatus Corydoras are omnivorous bottom feeders that primarily consume sinking pellets, algae wafers, and high-quality corydoras-specific foods. Supplement 2-3 times weekly with frozen foods like bloodworms, brine shrimp, or daphnia to ensure balanced nutrition. Feed small amounts daily, removing uneaten food after 2-3 hours to maintain water quality.

Behavior

These peaceful catfish are highly social and must be kept in groups of 6 or more to exhibit natural schooling behavior and reduce stress. They spend most of their time on the substrate sifting through sand for food, occasionally darting upward for floating particles. They are nocturnal to crepuscular, showing peak activity during dawn and dusk hours.

Breeding

Breeding Zygatus Corydoras in captivity is difficult and rarely achieved by hobbyists. Successful breeding requires pristine water conditions, cooler temperatures (around 72°F), and specific conditioning with live foods. Fry are extremely small and require infusoria or specialized fry foods; most captive breeding attempts fail due to egg fungus or parental stress.

Tank Mates

Otocinclus

Similar size, peaceful temperament, and bottom-dwelling habits make them ideal companions with identical water parameter needs

excellent

Neon Tetra

Small, peaceful mid-water swimmers that won't compete for bottom space and thrive in the same soft, acidic water conditions

excellent

Rummy Nose Tetra

Peaceful schooling fish that occupy mid-water zones and prefer slightly acidic water similar to Zygatus requirements

excellent

Red Cherry Shrimp

Peaceful invertebrates that occupy similar bottom zones; ensure adequate hiding spaces to prevent predation of shrimplets

Bolivian Ram

Peaceful dwarf cichlid with compatible water parameters; may occasionally chase corydoras but generally coexist peacefully

Common Diseases

Barbel Erosion (Whisker Disease)

Symptoms

Deterioration or complete loss of barbels; reduced feeding behavior; increased stress and hiding

Treatment

Perform 25-30% water changes weekly, improve substrate quality to fine sand only, enhance water quality with frequent testing, and provide high-quality varied diet to boost immunity

Ich (Ichthyophthirius multifiliis)

Symptoms

White spots on body and fins, rapid breathing, rubbing against substrate, lethargy

Treatment

Raise temperature gradually to 79°F, perform daily 25% water changes, use aquarium salt at half-dose (corydoras are salt-sensitive), or use ich-specific medication following label instructions carefully

Fin Rot

Symptoms

Frayed or disintegrating fins, white or cloudy fin edges, reduced activity

Treatment

Improve water quality through frequent partial water changes, maintain optimal temperature and pH, remove sharp decorations, and treat with antibacterial medication if condition worsens

Dropsy

Symptoms

Bloated abdomen, scales standing on end (pinecone appearance), lethargy, loss of appetite

Treatment

Isolate affected fish immediately, perform frequent water changes, maintain pristine conditions, provide high-quality varied diet, and treat with antibiotics if bacterial infection is suspected
