3 Corydoras, sold as 'julii' which neither of them are of course.
But what are they?
These first one leaves me clueless, the second looks to me as a trilineatus (though it's rather tiny and a bit battered up; but I'll fix him up) & the third one is a spitting image of C102, a species I already keep

I agree on the latter two. Can you get better pics of the first? Could be leopardus, which has smaller marks than C102.

Cheers, Eric

Thanks for the reply Eric, I'll do my best
