I haven't checked this thread in awhile. That particular fish is my white Calvus. The black has the black body with white speckling. I'll post a pic.The blue fish is mine well it was mine i no longer have them but it was a Kigoma Frontosa and that is what it was sold to me as when i bought it when it was a juvenile..
The black stripe one is Afro's fish and it is a black Calvus i too have these fish and are wonderful, i would stick with the Calvus they stay smaller than the Frontosa for a 55gal..
