Description
The Pygmy Cory is a peaceful little species, ideally suited to smaller softwater aquaria. Due to its diminutive adult size, it is not suitable for the general community aquarium as it may be intimidated by or preyed upon by larger tankmates. Mature, densely planted nano tanks would be perfect for this pretty, shoaling catfish. There should be a sandy substrate in order to protect the delicate sensory barbels, and some shady hiding spots amongst driftwood and broad leaved plants. Floating plants can also be useful in helping to diffuse bright lighting. Peat filtration will help to keep the water soft and acidic, and the tannins released will result in the fish showing their best colours. Unusually for a Corydoras catfish, this delightful species spends a good deal of time hovering in midwater. Pygmy Corys should always be maintained in large sized groups of at least 10 specimens; this will not only give them more confidence, but will result in a more effective, natural-looking shoal. Other tankmates could include tiny sized characins such as Ember Tetras, micro Rasboras (Boraras spp.), or small ornamental shrimps such as Red Crystals or Cherries. Frequent partial water changes are a must, as these fish can be very sensitive to elevated nitrate levels. Corydoras have the ability to breathe air intestinally, so a small gap should be left between the surface of the water and the cover slides in order for the fish to come up to the surface and take air in. It may do this numerous times per day.
