The Long Fin Bronze Cory Catfish (Corydoras aeneus) is a long-finned variety of the popular Bronze Cory, featuring the same peaceful personality and metallic bronze-green coloration with noticeably longer, flowing fins. Best kept in groups of 6 or more, Long Fin Bronze Corys are excellent bottom-dwelling fish for peaceful planted and community aquariums with soft substrate, stable water conditions, and non-aggressive tank mates.
The Long Fin Bronze Cory Catfish (Corydoras aeneus) combines the hardy, social personality of the classic Bronze Cory with elegant elongated fins. Its body typically displays bronze, olive-green, gray, and subtle metallic coloration, while the extended fins create a more graceful appearance as the fish moves across the aquarium floor.
Also known as the Longfin Bronze Cory, Long Fin Bronze Corydoras, or Long Fin Green Cory, this selectively developed variety makes an attractive alternative for aquarists who enjoy the classic Bronze Cory but want a fish with a more dramatic appearance.
Taxonomy note: This species has traditionally been known throughout the aquarium trade as Corydoras aeneus. Under newer scientific classification, the accepted combination is Osteogaster aenea. The Long Fin Bronze Cory is a long-finned aquarium variety of this species.

What Does a Long Fin Bronze Cory Catfish Look Like?
The Long Fin Bronze Cory Catfish has the familiar bronze-to-green metallic coloration of the standard Bronze Cory combined with noticeably longer, flowing fins.
The body may appear bronze, olive-green, gray, or slightly blue-green depending on aquarium lighting and viewing angle. The underside is generally lighter, while the upper body can display a beautiful metallic sheen.
Its extended dorsal, pectoral, pelvic, and tail fins create a more elegant silhouette than the standard Bronze Cory, making the Longfin Bronze Cory especially noticeable when swimming across an open section of substrate.
Long Fin Bronze Cory vs. Regular Bronze Cory
The primary difference between a Long Fin Bronze Cory and a standard Bronze Cory is fin length. Both belong to the same species and share similar adult size, temperament, social behavior, diet, and aquarium care requirements.
Long Fin Bronze Corys have selectively developed extended fins that give them a noticeably more flowing appearance. Because of these longer fins, extra care should be taken when selecting tank mates and aquarium decorations.
Choose peaceful tank mates that are unlikely to nip or damage the extended fins. Avoid sharp decorations and abrasive objects that could tear the fins while the Corys explore the bottom of the aquarium.
Long Fin Bronze Cory Behavior & Group Size
Long Fin Bronze Corys are peaceful, social bottom-dwelling fish that should not be kept alone. We recommend maintaining at least 6 Long Fin Bronze Cory Catfish together.
In a proper group, they can often be seen exploring the aquarium floor together, searching through the substrate for food, resting close to one another, and moving around the lower portion of the aquarium as a loose school.
Larger groups may display even more natural and confident social behavior when aquarium size and filtration allow.
Like other Cory catfish, Long Fin Bronze Corys may occasionally swim rapidly to the surface to gulp atmospheric air before returning to the aquarium floor. Occasional surface visits are a normal Cory behavior.
Ideal Aquarium Setup for Long Fin Bronze Corydoras
A 20-gallon or larger freshwater aquarium provides a practical starting point for a school of Long Fin Bronze Cory Catfish. Because these fish spend much of their time near the aquarium floor, horizontal bottom space is especially important.
A soft sand substrate or smooth fine gravel is recommended. Long Fin Bronze Corys use sensitive barbels around their mouths to search the substrate for food, so sharp or abrasive materials should be avoided.
Plants, driftwood, smooth rocks, shaded areas, and leaf litter can create a comfortable natural-style environment while still leaving open sections of substrate for the group to explore and forage.
Because this variety has longer fins, smooth aquarium decorations are particularly useful for reducing the chance of unnecessary fin damage.
Long Fin Bronze Cory Water Parameters
Long Fin Bronze Cory Catfish generally do well at temperatures around 70–81°F (21–27°C) with a pH of approximately 6.0–8.0.
More important than constantly adjusting the aquarium to reach an exact number is providing clean, stable water conditions. Keep Long Fin Bronze Corys in a fully cycled aquarium with appropriate filtration, good oxygenation, and regular water changes.
Ammonia and nitrite should remain at zero, and sudden changes in temperature or water chemistry should be avoided.
What Do Long Fin Bronze Cory Catfish Eat?
Long Fin Bronze Corys are omnivores and should receive a varied diet formulated for bottom-dwelling freshwater fish. High-quality sinking pellets, tablets, or wafers can form the foundation of their diet.
Their diet may also be supplemented with appropriately sized frozen or live foods such as brine shrimp, daphnia, bloodworms, and similar nutritious foods.
Long Fin Bronze Cory Tank Mates
The peaceful personality of the Long Fin Bronze Cory Catfish makes it suitable for many freshwater community aquariums. Tank mates should be peaceful, non-predatory, and comfortable within similar water conditions.
Potential tank mates may include peaceful tetras, rasboras, guppies, peaceful gouramis, compatible dwarf cichlids, other suitable Cory catfish, and many other non-aggressive freshwater community species.
Avoid aggressive fish and known fin-nipping species. The extended fins of the Long Fin Bronze Cory can be more vulnerable to damage than the shorter fins found on a standard Bronze Cory.
Why Choose Long Fin Bronze Cory Catfish?
- Long, flowing fins create an elegant appearance
- Bronze-green metallic coloration
- Peaceful temperament for community aquariums
- Active and entertaining bottom-dwelling behavior
- Excellent choice for planted freshwater aquariums
- Social behavior when maintained in a proper group
- Adaptable to a range of stable freshwater conditions

Before Buying Long Fin Bronze Cory Catfish
Long Fin Bronze Corys are social fish and should not be kept alone. Plan to keep 6 or more and make sure your aquarium is fully cycled before introducing them. Provide a soft substrate, smooth decorations, peaceful tank mates, stable water conditions, and enough bottom space for your Cory group to comfortably explore and forage.
