A large, striking, and somewhat atypical relative of standard Corydoras. Native to the highly oxygenated, cooler coastal streams of Brazil, they require sub-tropical temperatures and will stress or die in standard tropical tanks. They exhibit strong sexual dimorphism. Highly social, they must be kept on a soft sand substrate to protect their sensitive barbels.

Bearded Cory Varieties
Each variety inherits the species defaults above. Only differences are highlighted.
Male
Males grow significantly larger, possess striking contrasting black-and-gold patterns, and develop distinct bristles (odontodes) on their cheeks. Unlike standard Corydoras, males can be mildly territorial with each other over females, so providing ample floor space is recommended.
Differs in 2 traits from base species
Also known as: Male Bearded Cory, Bristle Cory
Female
Females are smaller, have a more mottled and subdued pattern, and lack cheek bristles. They are extremely peaceful and should ideally outnumber or equal the males in a group.

Bearded Cory Care Guide Summary
The Bearded Cory, scientifically known as Scleromystax barbatus, belongs to the Catfish family group. Adults reach a maximum size of approximately 9 cm and have a depressed body shape with a moderate growth rate. Classified as peaceful, this species primarily occupies the bottom zone of the aquarium and produces a low level of biological waste.
To thrive, the Bearded Cory requires a freshwater only aquarium with a minimum volume of 110 litres and a tank length of at least 90 cm. Water temperature should be maintained between 16°C and 23°C, with a pH range of 6–7.4 and a general hardness of 2–12 dGH. A moderate water flow is preferred.
The Bearded Cory is a rewarding species to keep, provided its core environmental needs are met. This species is available in 2 varieties: Male and Female. Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.
Bearded Cory Habitat Setup
When setting up an aquarium for the Bearded Cory, a moderate water flow best suits their natural preferences. Because this species occupies the bottom zone, the aquarium layout should prioritise sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour.
Bearded Cory Compatibility Notes
Classified as peaceful, the Bearded Cory is a schooling species that feels most secure in a sizeable group, where natural shoaling behaviour reduces stress and brings out their best colours. When choosing tankmates, their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the bottom zone can help reduce competition and territorial overlap.
Who Bearded Cory Is Actually For
Bearded Cory is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide a keeper who can commit to a proper group of at least 6. It makes the most sense for a hobbyist who will actually build around its needs, especially sand.
The most common mistake is treating Bearded Cory like any other community fish and skipping the soft sand it needs to forage safely. Another frequent problem is underestimating its social needs. A token pair or trio often behaves very differently from a real group.

Fish Similar to Bearded Cory
Peppered Corydoras
Corydoras paleatus
One of the most popular and hardy Corydoras species. Notably, they prefer cooler water temperatures than most tropical fish. They are peaceful, bottom-dwelling schooling fish that use their sensitive barbels to sift through the substrate for food. They must be kept in groups to thrive.
Hi Fin Peppered Cory
Scleromystax macropterus
A spectacular armored catfish native to the fast-flowing, cool-water streams of southern Brazil. Unlike most tropical catfish, it strictly requires sub-tropical temperatures (16-23°C) and high dissolved oxygen. Frequently confused with 'long-fin' mutations of the standard Peppered Cory (C. paleatus), this is a naturally occurring, highly sexually dimorphic species.
Parallel Cory
Corydoras parallelus
A highly sought-after and relatively rare Corydoras species native to the upper Rio Negro basin. They are instantly recognizable by the striking black and white parallel stripes running along their flanks. Like all Corydoras, they are peaceful, strictly bottom-dwelling shoaling fish that must be kept in groups. They require a soft sand substrate to protect their delicate barbels as they forage for food.
Lacerda Cory C015
Scleromystax lacerdai
A rare and beautiful bottom-dweller endemic to coastal Brazilian streams (Bahia). Unlike typical tropical Corydoras, it is a temperate/sub-tropical species that requires cooler water (20-25°C). They are highly sexually dimorphic and must be kept on a soft sand substrate to protect their delicate sensory barbels.
Black Fin Cory
Corydoras leucomelas
A peaceful schooling catfish native to the Amazon basin, easily identified by its black dorsal fin and a dark mask-like band across its eyes. Like all Corydoras, they are bottom-dwellers that use sensitive barbels to forage. They possess a modified intestine allowing them to gulp atmospheric air, so occasional darts to the surface are normal. They are highly social and require a soft sandy substrate to prevent barbel erosion.
Loxozonus Corydoras (C079/C082)
Corydoras loxozonus
A peaceful, bottom-dwelling catfish native to the Rio Meta basin in Colombia. Known for the distinctive diagonal black stripe across its back and a mask over its eyes. Like all Corydoras, they are highly social and must be kept in groups. A soft, sandy substrate is strictly required to prevent damage to their delicate barbels as they sift for food.
