Ricordea is split up into two groups- Ricordea yuma and Ricordea floridia. floridia comes from the carribean and yumas come from the pacific. They look distinctly different from each other, someone will probably post pics. And yumas, on average, are much more expensive per polyp than floridias.
They are both mainly photosynthetic and need high light to thrive and grow. If they are in moderate to lower light they are likely to live but not grow or if they do it's really slow growth. You can feed them zooplankton and meaty foods, but lighting is much more important than feedings.
