Variety of Bronze Corydoras · GloFish

📍 Captive-bred (hybrid)

Ask Finn

GloFish Corydoras are fluorescent variants of the Bronze Corydoras, engineered to glow under blue LED or UV lighting. They are the same peaceful, bottom-dwelling schooling catfish as their wild-type counterparts — best kept in groups of 6+ and excellent community fish. They scavenge leftover food and help keep the substrate clean.

Care Guide

Diet

GloFish Corydoras are omnivorous bottom feeders that consume sinking pellets, algae wafers, and frozen foods like bloodworms and brine shrimp. Feed small amounts once daily, providing only what they can consume in 2-3 minutes. They will scavenge leftover food from the substrate, supplementing their diet naturally.

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 gravel and sand in search of food, and are most active during dawn and dusk. Under blue LED or UV lighting, their fluorescent coloration creates a striking visual display.

Breeding

Breeding GloFish Corydoras in captivity is difficult and rarely successful in home aquariums. They require specific water conditions, cooler temperatures (around 72°F), and plenty of hiding spaces with fine substrate for spawning. Most specimens in the hobby are commercially bred, and natural reproduction is uncommon.
