Lighting calculations

[WWWD]

Mushrooms yes, frogspawn, maybe might loose some colour. Ricordia, no way, they love light and lots of it.

[Synthesis]

I would recommend Metal Halide for ricordia. They just seem to do much much better in bright light. I would move the yuma as high up in the tank as possible and see how it does.

Otherwise your light setup should be fine for mushrooms and leathers.
