Mushroom ID please

[paul.o]

Got these when they were tiny, sold as bouncing mushrooms, which they appear to be, started off with two and now have about six, as they seem to be multiplying fairly quickly I am a bit apprehensive about placing them on my main rock rock and have them currently on a small island which is where they will stay I think.

They look like Gonzo Golden Dragons to me! They are beautiful but can be a bit invasive. Best practice is to keep them isolated from the main rockwork, a local reefer had to dismantle a portion of his scape to remove some that were attacking his acros.
