Sold as a pair of vieja synspillum but upon further info search, I have my doubts...definitely not syns. Confused between hartwegi or bifasciatus? Their lower dark markings appear when stressed (during water changes).

They are very compatible and looks like they will soon spawn in a 150 gal all to themselves. Just love their colors. Any help will be appreciated.

Thanks for the clarification everyone. Will update on the pair again soon. Hope to have some little ones to report.
 
they are Bifas. They look nice. There are variants of bifas also.
 
Agree with bifas. I have two males - one whose lateral line will also disappear during WCs & one that is always solid.
