Aspidoras pauciradiatus
Also known as false corydoras, bluefin cory, blue fin aspidoras, aspidoras c37, pauciradiatus cory, sparse-rayed aspidoras, アスピドラス・パウキラディアトゥス, 少鳍盾皮鲇

A tiny armoured catfish resembling a slim Corydoras, with a pale body, fine dark spotting and a dark blotch on the dorsal fin that can show a bluish sheen. It is kept for its lively, busy shoaling behaviour along the substrate and suits small, peaceful soft-water community tanks.

Breeding
An egg scatterer that lays adhesive eggs on plants and glass, much like Corydoras, often after a cool water change. Spawning happens occasionally in well-kept groups, but raising the very small fry needs infusoria-sized foods and clean water, so it is moderately difficult.
Good to know
Needs fine sand and good water quality, as barbels erode on sharp gravel. Fish sold under this name are often mixed with similar Aspidoras or Corydoras species, so check identification.
