That was the first place I looked, it's conveniently located, even for a dope like me. The lighting is so different in the photo there where fish are about the same size as the ones I saw, so I felt it made it difficult to judge. The juvy in this link seems to have been photographed under similar lighting, looks similar to the ones I posted, and is ID'd as a Kelberi as well:
