Albino Pygmy Corydora

Albino Pygmy Corydoras | A Tiny and Charming Nano Bottom Dweller

The Albino Pygmy Corydoras (Corydoras pygmaeus var. Albino) is a captivating and endearing little fish that brings all the personality and industrious charm of the Corydoras family in a miniature, pale package. A selectively bred albino variant of the Pygmy Corydoras, these tiny fish display a creamy white to pale pink body with distinctive pink-tinged eyes that catch the light beautifully — an ethereal, delicate appearance that stands out especially well against dark substrate and lush green planting.

Unlike most Corydoras species that stick to the bottom, Pygmy Corydoras are active mid-water swimmers that school together in open water as well as forage along the substrate — making them one of the most entertaining and visually dynamic small fish in the nano aquarium hobby.

Albino Pygmy Corydoras Tank Setup

Fine sand or very smooth substrate is essential — their delicate barbels are easily damaged by sharp gravel, which can lead to infections and long term health problems. A well-planted nano aquarium with open sandy areas, floating plants to diffuse lighting, driftwood, and hiding spots suits them perfectly. Gentle filtration is important — these are small fish from slow-moving waters and strong flow can stress them. A sponge filter is ideal, providing gentle water movement, additional biofilm grazing surfaces, and no risk to small fish.

Feeding Your Albino Pygmy Corydoras

Omnivorous micro feeders that forage constantly throughout the day. High quality sinking micro wafers and small pellets form an excellent staple, supplemented with frozen or live foods such as baby brine shrimp, micro worms, daphnia, and cyclops. Food size matters — standard sinking wafers should be broken into smaller pieces to suit their tiny mouths. Feed small amounts twice daily and remove uneaten food promptly to maintain water quality.

A Note on Groups

Pygmy Corydoras are highly social and genuinely thrive in large groups — the difference in confidence, activity level, and schooling behaviour between a group of 6 and a group of 15 is remarkable. If space allows, more is always better with this species. In a large group they will school actively through the mid-water column together, producing a beautiful, shimmering display that few other nano fish can replicate.

Albino Pygmy Corydoras Tank Mates

• Small, peaceful nano fish such as Chili Rasboras, Ember Tetras, and Celestial Pearl Danios
• Dwarf shrimp such as Neocaridina and Caridina — excellent tank mates
• Nerite snails and other small snail species
• Other Corydoras species in larger setups
• Avoid any fish large enough to eat them — their tiny size makes tank mate selection critical
• Avoid boisterous or fin-nipping species
• Avoid strong filtration or water flow that will stress these small fish
