I know it has become a sort of Zoochat cliche to criticise what is on zoo signs, but why does Corydoras sterbai just get the common name "Cory Catfish"? That is so lazy.
The species to the left, Corydoras duplicareus, gets a proper common name even if it is probably wrong (I've not heard it called Black Bar Corydoras before, so I think they've probably got confused with its usual trade-name of Black-Back Corydoras), so why not give sterbai the same consideration?
