Flag Tailed Panda Cory Catfish – Corydoras Oiapoquensis

The Flag Tailed Panda Cory Catfish (Corydoras oiapoquensis) is a beautiful short-snouted Cory-type catfish that combines the familiar black-and-cream pattern of a Panda Cory with an eye-catching striped caudal fin.

Also known as the Flag-Tailed Panda Cory, Stripe Tailed Panda Cory, Oiapoque Cory, or Oiapoque Corydoras, this species has long been prized by Cory enthusiasts for its distinctive combination of facial mask, dorsal marking, and tail pattern.

The body is typically pale cream, beige, silver-gray, or lightly pinkish. A dark band crosses the eye, producing the recognizable “panda” appearance, while the caudal fin develops several dark bands that create the flag-like pattern responsible for its common name.

Taxonomy note: This species was described in 1972 as Corydoras oiapoquensis and remains widely known by that name throughout the aquarium hobby. Following the 2024 revision of Corydoradinae, it was transferred to the resurrected genus Hoplisoma. Specialist Cory references commonly use Hoplisoma oiapoquense, while some major databases currently index the combination as Hoplisoma oiapoquensis. The traditional name Corydoras oiapoquensis remains especially useful for aquarium identification and SEO.

Flag Tailed Panda Cory Catfish Care Information

What Does a Flag Tailed Panda Cory Look Like?

The Flag Tailed Panda Cory has a compact, short-snouted body with a pale cream, sandy beige, silver, or lightly pinkish base color.

A bold black mask passes through the eye, creating the panda-like facial pattern that immediately gives this fish a resemblance to the famous Panda Cory.

A dark marking is also present around the dorsal-fin region, while the tail fin develops a series of dark wavy or broken bands. These contrasting bands create the striped “flag tail” appearance for which the species is named.

Pattern intensity can vary naturally between individuals. Some populations and aquarium lines may show differences in the amount of dark pigmentation on the dorsal area, caudal peduncle, or tail.

Why Is It Called the Flag Tailed Panda Cory?

The “Panda Cory” part of the name comes from the dark eye mask and pale body, which resemble the pattern of Hoplisoma panda.

The “Flag Tailed” part refers to the distinctive dark bands running across the caudal fin. These bands can appear wavy or broken and create a striped pattern that looks very different from the mostly clear tail of a standard Panda Cory.

Flag Tailed Panda Cory vs. Panda Cory

The Flag Tailed Panda Cory (Corydoras oiapoquensis) and the common Panda Cory (Corydoras panda) can look similar at first glance, but they are separate species from very different parts of South America.

Both species have pale bodies and dark facial markings, but the Flag Tailed Panda Cory develops a strongly banded caudal fin.

The common Panda Cory typically has a largely clear tail fin and a prominent dark marking at the caudal peduncle near the base of the tail.

In Corydoras oiapoquensis, the tail itself is a major part of the pattern, making the fish especially easy to recognize once the two species are compared side by side.

Flag Tailed Panda Cory vs. Brochis Condiscipulus

In the wild, the Flag Tailed Panda Cory occurs alongside a remarkably similar-looking species historically known as Corydoras condiscipulus.

The two can occur in the same schools, which is reflected in the name condiscipulus, meaning approximately “schoolmate” or “fellow pupil.”

The most obvious external difference is head shape. The Flag Tailed Panda Cory has a shorter, blunter snout, while the condiscipulus-type fish has a much longer snout.

Under the modern Corydoradinae classification, these two look-alikes are even placed in different genera, reflecting their distinct evolutionary lineages.

Is Corydoras Oiapoquensis Now a Hoplisoma?

Yes. Corydoras oiapoquensis was historically placed in the large genus Corydoras.

Modern genetic and morphological work demonstrated that the traditional Corydoras grouping contained several separate evolutionary lineages. In the major 2024 revision of Corydoradinae, this short-snouted lineage was transferred to the resurrected genus Hoplisoma.

Specialist Cory references therefore commonly use Hoplisoma oiapoquense. Some major biological databases currently index the spelling Hoplisoma oiapoquensis. The established aquarium name Corydoras oiapoquensis remains useful for customer recognition and search visibility.

Flag Tailed Panda Cory Behavior & Group Size

Flag Tailed Panda Corys are peaceful, social bottom-dwelling fish and should not be kept alone.

Keep at least 6 Flag Tailed Panda Cory Catfish together. A proper group generally encourages more confident, active, and visible behavior.

This species can be somewhat shy, particularly when recently imported or kept with large, boisterous fish. A peaceful environment with plenty of cover and several members of its own species helps the fish feel secure.

Like other Cory-type catfish, Flag Tailed Panda Corys may occasionally make a rapid trip to the water surface to gulp atmospheric air before returning to the bottom. Occasional surface visits are normal.

Ideal Aquarium Setup for Flag Tailed Panda Cory Catfish

A 20-gallon or larger aquarium provides a practical starting point for a group of six or more Flag Tailed Panda Corys. Horizontal bottom space is more important than tank height.

A fine sand substrate is highly recommended. Smooth, rounded fine gravel may also be used when kept exceptionally clean, but sharp or abrasive substrate should be avoided.

These Corys naturally search the substrate using sensitive barbels, so a clean, soft aquarium floor helps support natural foraging behavior.

Driftwood, smooth stones, live plants, floating plants, shaded areas, and open sections of sand can create an excellent aquarium environment.

Gentle-to-moderate water movement and good surface agitation are useful because this species benefits from clean, well-oxygenated water.

Where Do Flag Tailed Panda Corys Come From?

The Flag Tailed Panda Cory is native to the Oyapock River basin, also spelled Oiapoque, along the border between French Guiana and Brazil.

Scientific records place the species in the upper portions of the drainage, including areas upstream of major rapids.

The type locality is associated with Cumuri Creek on the left bank of the Rio Oiapoque in French Guiana.

This relatively restricted natural distribution makes the species especially interesting to Cory enthusiasts interested in geographic locality and naturally occurring species diversity.

Flag Tailed Panda Cory Water Parameters

Flag Tailed Panda Cory Catfish do well at approximately 73–79°F (23–26°C) with a pH around 6.0–7.2.

Soft to moderately hard water can be suitable, but water quality and stability are more important than constantly adjusting the aquarium to reach one exact number.

Keep the aquarium fully cycled with effective biological filtration, good surface agitation, and regular water changes.

Ammonia and nitrite should remain at zero. Dirty substrate and poor long-term water quality should be avoided because Cory barbels and overall condition can deteriorate in neglected aquariums.

What Do Flag Tailed Panda Cory Catfish Eat?

Flag Tailed Panda Corys are omnivorous foragers and readily accept a variety of appropriately sized aquarium foods.

High-quality sinking pellets, tablets, or wafers can form the foundation of their diet. Supplement prepared foods with frozen or live foods such as:

• Bloodworms
• Brine shrimp
• Daphnia
• Blackworms
• Tubifex
• Other appropriately sized sinking foods

Feed enough that the entire group receives food. Larger or faster midwater fish should not be allowed to consume everything before sinking foods reach the Corys.

Flag Tailed Panda Cory Tank Mates

The peaceful temperament of the Flag Tailed Panda Cory Catfish makes it suitable for carefully planned freshwater community aquariums.

Potential tank mates may include peaceful tetras, pencilfish, rasboras, small danios, peaceful dwarf cichlids, small gouramis, other compatible Cory-type catfish, and other non-aggressive freshwater species with overlapping water requirements.

Avoid large, aggressive, highly territorial, or excessively boisterous fish. Flag Tailed Panda Corys can be relatively shy and may stop feeding confidently when intimidated by much larger tank mates.

Male vs. Female Flag Tailed Panda Cory

Adult males and females can be distinguished more easily once the fish reach maturity.

Males generally remain somewhat smaller and slimmer, reaching approximately 2 inches.

Females can reach approximately 2.2–2.25 inches and usually become broader and heavier through the body.

The difference is often easiest to see when mature fish are viewed from above, especially when females are in breeding condition.
