I know. Its got me a bit confused. I've got it growing out with 5 Rio meta orinos. This mystery fish has even more distinct diamonds than my metas.. Its about 2.5-3" now guess we will see after I fatten it up a bit
When they're that small monos, ocell and even kels vertical lines kinda look diamond shape but become more pronounced with time. Shouldn't take long. I think it will be an O though, the heads got me buggn though
I find that most, if not all orino's share a trait in the eyes. This trait is, the eye, if drawn a straight line from the front of the eye down towards the mouth.....it will line up evenly. Now, if this is done with monos, ocells, pleiazona's, kelberi's and negors and such.....if drawn a straight line from the front of THE BLACK of the eyes down towards the mouth, it will line flush (more or less).
So looking at your bass, To me, it looks to be mono or ocell type.
These are pictures of my older stock, lets see if you can determine the bass by the description I have learned......ENJOY.
