FYI many many Corys are sold as C. julii that are not. Julii have a well known name. Any spotted Cat is often passed off as C julii. C trilineatus is a common "false" julii. True julii have tiny spots on their faces. Check Planet Catfish for pics of real C julii.
I would check Planet Catfish. It looks like a Corydoras rather than a Brochis species.
