I got a couple corydoras from petsmart 2 weeks ago, 3 juliI (most likely false from what I hear) and 2 albino after being told they would school even though they had different coloring. They don't really and despite having black sand I like how the juliI look more so I decided to get more. Sadly petsmart had only 2 when I went to get more. Strangely when I got home and got them in my 29 gallon I realized they look very different. My original trio look more grey, small and spotted versus the new pair were very white and the dots were more connected lines. They haven't really schooled up so if they are different than false juliI I want more of the slightly darker grey ones I guess. First pic is one of the original 3 and the last is the new one. Please help me ID of both are false julii!
