Yes, most certainly a juvenile fish. Unfortunately we don't have a picture of the adults, or access to the fish as it matures.
I may end up contacting the importer/breeder directly to see if we can get pictures of the fish this one was bred from...however in the past I have found this to "ruffle the feathers" of importers...even those considered to be "reputable".
...Then again...those of you that know me...know I'm really not too shy about "ruffling feathers"
I'm not an aquatic biologist...I just play one on the internet.
