fire urchin help

[Teaggs]

They all said they never see them. One store said he can try but guarantee it will be like the one I want. The rarest ive seen is a flower urchin the other day.

 

[Calappidae]

I've seen them labeled as "Red longspine urchin" or "radiating urchin" as well.. my lfs goes by radiating and so does diver's den so maybe try that one for better odds.
