If you read that thread you will also see that kevin kohen believes that both are the same spexies as rubriventralis. And whether you believe they are the same species or not, the physical attributes, such as color and pattern are different enough between the varieties, as to be able to visually differentiate rubriventralis, sp.2, and sp. 3.
All i did was point out that sp. 3 has a yellow margin and black fins. If it is its own species someday, fine, if it is the same as sp. 2 and rubriventralis, fine. All im saying is there are visible diffeences.
