Was at one of my lfs's today. This guy always has the best selection of Rainbows (10-12 species) around and today he had a new one. It is M.parva. He calls it the flame rainbow and boy is it beautiful! The great thing about it is that it stays small for a rainbow (~2"). I ended up getting four of them, 2 males and two females. Up to now the boesmani was my favorite rainbow but I think that is going to change! Link to a Picture
