No they're not wild caught.Interesting!
My normal sterbai tend towards skittishness too, old cory expert friend suggested they may be wild caught sterbai. I don't know how often sterbai in the trade are wild caught vs tank raised, since they're apparently not that hard to breed either... but albinos will definitely have been captive bred, any chance your normal sterbai might have been wild caught?
It quite weird sometimes. You could have outgoing Corys, you make a slight change in your tank and suddenly they are skittish as .... C.sterbai is known about such sudden changes in behaviour. Must have to do with Feng Shui somehow hahaha.
