Just came across this free E-book on Corydoras Catfish in a FaceBook Group called “Corydoras Vault Singapore“.
It is very comprehensive, and shows rare Corydoras that many people do not know even exist. It is fascinating how many species of corydoras “armored catfish” there are.
Something I learnt from the book is that Corydoras is named from Greek “kory” which means helmet, and “doras” which means skin.
Do download this free E-book (while it is still free):
