Can you show a source that states all rotkeils have the features you mention? Have the fish been officially described yet? I don't recall seeing this before so I'm curious. Out of all the severums I've seen and owned, very few have yellow anal fins.
By the way, I think H. appendiculatus has been collapsed into H. efasciatus and is no longer valid.
