Green Laser Corydoras

Corydoras sp. 'CW009'

AnimaliaChordataActinopterygii

📍 South America

Ask Finn

An undescribed Corydoras species (CW009) from Peru featuring a striking neon-green iridescent stripe running from snout to tail base against a darker body, giving it an almost laser-beam appearance. Highly sought after by corydoras enthusiasts, it requires the same care as other corydoras: groups of 6+, fine sand substrate, and clean, well-oxygenated water.

Care Guide

Diet

Green Laser Corydoras are omnivorous bottom feeders that consume sinking pellets, algae wafers, and frozen foods like bloodworms and brine shrimp. Feed small amounts once daily, ensuring food reaches the substrate where they forage. They also benefit from occasional vegetable matter and will scavenge leftover food from other tank inhabitants.

Behavior

These peaceful catfish are nocturnal and most active during dawn and dusk, spending much of their time sifting through the substrate in search of food. They are social fish that should always be kept in groups of 6 or more to reduce stress and encourage natural schooling behavior. They rarely interact with other fish but may occasionally interact with tankmates during feeding times.

Breeding

Breeding Green Laser Corydoras in captivity is difficult and rarely documented due to their undescribed status and specific environmental requirements. Successful breeding would likely require cooler water temperatures (around 72°F), pristine water conditions, and conditioning with live foods. Fry care would be challenging, as with most corydoras species, requiring infusoria and micro foods.

Common Diseases

Ich (Ichthyophthirius multifiliis)

Symptoms

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

Treatment

Raise temperature gradually to 79°F, perform daily 25% water changes, use ich medication following label instructions; maintain excellent water quality

Fin Rot

Symptoms

Frayed or deteriorating fins, discoloration at fin edges, fin loss

Treatment

Perform 50% water change immediately, improve water quality and aeration, treat with antibacterial medication if severe; ensure substrate is clean and soft

Barbel Erosion

Symptoms

Shortened or missing barbels, difficulty locating food, behavioral changes

Treatment

Improve substrate quality by using fine sand instead of gravel, enhance water quality with frequent changes, ensure adequate nutrition with varied foods

Bacterial Infection

Symptoms

Open sores, cloudy eyes, loss of appetite, lethargy, discoloration

Treatment

Perform 50% water change, maintain pristine water conditions, treat with broad-spectrum antibacterial medication; isolate if possible to prevent spread
