The title says it all my uncle gave my mom this rock with all these mushrooms on it to put in my tank i was just wondering what kind they are they kinda of look like ricordia or yuma but i'm not sure can anyone help there a whole bunch of them!!!
They are Ricordea Yumas. There are two types of ricordeas that show up in the reef aquarium industry ricordea floridas and ricordea yumas. The proper way to spell ricordea is with an "e" despite common misspelling as ricordia. Don't mean to be a snob but I just thought people should know because having two ways of spelling the same thing only makes it hard to find when using search functions.
