C. gossei vs CW069

I received my group of 14 adult fish from a single shipment of about 60 wild fish. They were labeled Corydoras gossei and imported into the USA thru Adolfo Schwartz to White’s Fish Farm in Mogadore Ohio in 1995. Of the 14 fish, 11 of them looked the same, as in having a solid dull brown (milk chocolate brown) color on the upper portion of their body with a dull white underside. I assumed that these, since they were the majority, were the C. gossei and I kept separate from the others.
