Hello. New to forum. What a nice community.

Q:

Anyone have any ideas on how long an aquarium should be running (established ) before introducing Blue legged or Electric blue banded hermits ? Im wondering in lieu of their diet.

Q2:

Has anyone successfully kept Electric Blue Banded Hermits and/or Blue Legged Hermits with P. Volitan Lionfish?

Setup Plan:
Im planning on setting up 90g w/ single P. Volitan lionfish, one toadstool leather coral, and substrate and live rock.
