Nice find, thanks!Hi luke,
Have a look at this site to id your cory http/www.nettaigyo.com/corydoras/encyc/index-e.html it has loads of corys so it might take a while to look through them all

cuold you get a better picture of the cory ? that might help people make a correct identification as it could be c.trilineatus which is often mixed up for c.julii the main differance is c.julii have spots where as c.trilineatus have small lines
