Description

Fuller’s Cory (Corydoras fulleri)

Overview

Fuller’s Cory is a rare and attractive Corydoras species known for its elegant patterning, subtle metallic sheen, and calm temperament. As an active bottom-dweller, it brings constant movement and charm to peaceful community aquariums. Its rarity in the hobby makes it a prized choice for Cory collectors and planted-tank keepers.

Origin

Found in freshwater tributaries of South America, particularly in Peru. It inhabits soft, clean, slow-moving waters with sandy substrates and leaf litter.

Feeding

Omnivorous and easy to feed:

  • Sinking micro-pellets and catfish wafers

  • Frozen foods (bloodworms, cyclops, daphnia, brine shrimp)

  • Occasional live foods for conditioning
    Avoid feeding only floating foods—them being bottom feeders, they prefer food that sinks.

Tank Mates

Ideal for peaceful community setups with:

  • Small tetras and rasboras

  • Dwarf cichlids (e.g., Apistogramma, Mikrogeophagus)

  • Peaceful livebearers

  • Other Corydoras species

  • Small peaceful loaches

Avoid: Large or aggressive fish that may outcompete or intimidate them.

Aggression

Very low. Corydoras are peaceful schooling fish and should be kept in groups of 6 or more for best natural behavior.

Experience Level

Beginner to Intermediate. Hardy once established, but appreciates good water quality and a soft sandy substrate to protect their barbels.

Water Parameters

  • Temperature: 72–79°F (22–26°C)

  • pH: 6.0–7.5

  • Hardness: 2–12 dGH

  • Notes: Provide gentle filtration, sand substrate, and plenty of hiding areas using plants, driftwood, and leaf litter.

Fuller’s Cory (Corydoras fulleri) is a rare and peaceful bottom-dweller that brings personality and beauty to calm, well-maintained community aquariums. Perfect for enthusiasts and Cory collectors.
