Thanks for the help, I contacted the seller and told them. They said the issue they had with it being similis was to do with its color. I for one agree that it is a similis after all though.

This corydoras was listed as corydoras sp. at a fish store. I was hoping I could get help figuring out the species before I purchase the fish.
