Rock for an anemone

[HouseDJSTL]

I thought I remembered seeing a man-made rock that had a "crater" in the middle of it that an anemone would naturally take to?

Was I seeing things?

Thought it was BRS, but can't find anything.....

Anemones won't usually sit where we want them to unless it happens to likes the environment where it is (no matter what rock you use). I put mine in a clay pot with sand and he stays put.

Okay I found it. This time I googled 'cradle' as a keyword.
Honestly, looks like something one could make with putty, glue and some crushed coral. I'm surprised but reviews seem to suggest nems stay put in it.
