The fish labeled as Mark's sunshine is a sunshine peacock i bought from him about 9 months ago. He is very orange compare to my other sunshine peacock, almost as orange as my rubenscens which i got from organism.
yes, sunshine are more yellow. however according to this page http://www.cichlid-forum.com/articles/red_peacocks.php , the sunshine and the rubenscens are basically the same type of fish, rubenscens are line breed from selected sunshine peacock that has more orange/ red in them.
Thank you, however, both of them are not as nice looking now after i put them in my main tank with bigger/ more aggressive fish :-?
