No problem you were told they were FF you had no reason to think otherwise. These fish have been known to be mixed up with each other. One time I bought a bunch of 1" SAE from a store. Later to find out after closer inspection some were FF mixed with SAE. When there really little its hard to tell apart and when a store you trust says there SAE you trust them. Its not really there fault there wholesaler sold them as SAE. I went back to tell the owner. He said one of his employees put the FF into the wrong tank mixed them with the SAE tank. So anyways I had a hell of time catching them out of my densely planted tank. They don't do any damage but they don't do any good either for what I want. So I wanted them out of my tank
