Reef nutrition

Anyone know what type of ricordia this is ?

Definitely a green/brown Yuma. Generic way to tell them apart from what? Florida? Yumas are definitely more plump and the mouths stick out. Maybe someone can find a link to something more scientific :)
 
R. yuma tends to have tentacles up on and around the mouth of the polyp; R. florida lacks such.
On R. yumas, I have also noted the notable difference in tentacle size, and spacing on the oral disc of the polyps compared to R. florida ... could be just me though.
