Description

Sterbai Corydora – Corydoras sterbai

The Sterbai Corydora is one of the most attractive and popular bottom-dwelling catfish in the aquarium hobby. With its intricate white spotting, dark body markings and distinctive orange pectoral fins, this peaceful South American species makes a wonderful addition to a well-maintained tropical community aquarium.

Native to the waterways of Brazil and Bolivia, Sterbai Corydoras are active, sociable fish that spend much of their time exploring the aquarium floor in search of food. They are particularly valued for their ability to tolerate warmer water than many other Corydoras species, making them one of the better choices for aquariums containing Discus.

Sterbai Corydora Aquarium Set Up

A soft sand substrate is strongly recommended for these bottom-dwelling catfish. Sterbai Corydoras naturally sift through the substrate using their sensitive barbels, and sharp gravel or accumulated debris can cause damage and infection.

We recommend an aquarium of at least 90 litres for a group of six, ideally with plenty of open floor space for foraging.

Decorate the aquarium with bogwood, smooth stones and live plants to provide sheltered areas while leaving open sandy spaces for exploration. Good filtration, regular water changes and a clean substrate are particularly important for maintaining healthy Corydoras.

Although they appreciate gentle water movement, the aquarium should also be well oxygenated, especially when maintained at higher temperatures.

Sterbai Corydora Behaviour

These charming little catfish are extremely sociable and should always be kept in groups of at least six. Larger groups often display more natural behaviour, with individuals exploring together, resting alongside one another and occasionally making sudden energetic dashes around the aquarium.

When kept in insufficient numbers, Corydoras can become timid and spend much of their time hiding.

Like other Corydoras, Sterbai possess the unusual ability to take occasional gulps of atmospheric air at the surface. This is perfectly normal behaviour, although frequent or distressed surface visits can indicate poor water conditions or inadequate oxygenation.

Despite their reputation as scavengers, Corydoras are not aquarium cleaners and must receive their own nutritious diet.

Sterbai Corydora Tank Mates

Their peaceful temperament makes Sterbai Corydoras excellent companions for many community fish.

Suitable tank mates include:

• Discus – one of the more suitable Corydoras species for warmer Discus aquariums.
• Angelfish – generally compatible in appropriately sized aquariums.
• Tetras – peaceful species such as Cardinals, Rummynose and Emperors.
• Rasboras – active but generally peaceful community companions.
• Dwarf Cichlids – suitable species such as Apistogramma, provided territories and floor space are considered.
• Other peaceful community fish – particularly species occupying the middle and upper water levels.

Avoid large predatory fish, aggressive cichlids and particularly boisterous bottom dwellers that may compete for food or territory.

Feeding Sterbai Corydoras

Sterbai Corydoras are omnivorous and readily accept a varied diet.

Good-quality sinking catfish pellets, granules and wafers should form the basis of their feeding routine. Supplement these with frozen or live foods such as bloodworm, brineshrimp and daphnia.

Because they spend most of their time near the substrate, ensure food reaches the aquarium floor rather than being consumed entirely by fish feeding above them.

Water Parameters and Care

Sterbai Corydoras prefer stable, clean water and are particularly well suited to established tropical aquariums.

Their ability to tolerate temperatures of approximately 24–28°C makes them a popular choice for warmer community setups, although adequate oxygenation becomes increasingly important towards the upper end of this range.

They are generally straightforward to care for when provided with suitable conditions, a proper diet and the company of their own species.

With their beautiful markings, peaceful nature and endlessly entertaining behaviour, the Sterbai Corydora is a fantastic choice for aquarists looking to bring activity and character to the lower levels of their aquarium.
