This species on first sight could be misconstrued as Corydoras aeneus but the longer overall body shape and the yellow/ochre fins tell them apart. They used to be a common sight in aquatic shops up and down the country but the last few years they have been very thin on the ground and as such should be snapped up if seen in your local LFS.
The green body colouration really abounds when they are in good condition and in breeding mode.
The original type locality of Tolimais in Colombia, Honda Province in the Río Magdalena basin, is doubtful as collectors have been unable to find this species there. However, collections are made from the Río Meta basin.
Males are more slender than the females and the ventral fins in the female are rounded whilst the males are pointed.
Not one of the easiest Cory's to breed but will spawn as per the genus. They will lay up to 150 eggs and the larvae will hatch after 5 days. Mark Bryson from Paisley, Scotland has been successful with this species, read his article here.
