well just a few examples, they have a tank in my lfs of 'mixed corys' comprising of bronze corydoras, albino corydoras and peppered corydoras for £1.50 each, panda cory's are £1.50 each, they did have pygmies but i think they have all gone for £1.50, i think sterbai are the most expensive in there and they are £4 each, they have juli, axelrodi, adolfi, agassizzi, armatus, habrosus, metae, paleatus, punctatus, reynoldsi, rabauti, sodalis, schwartzi, trillineatus, venezuelans and weitzmani and there just the ones i can remember lol, and as i said the most expensive is £4.
i go some place's and am really shocked at some price's, as i am with some mentioned here!
looks like i could make a living out of buying and selling corydoras lol!
