Lunare Wrasse in a Bare Bottom tank

[hqgc]

I am starting to see an increase in cyano in my fowlr. I was wondering how my lunare wrasse would do without sand. He does "dive-bombs" in and out of the sand and wondering if I took out the sand if this would affect the wrasse.
He is a great fish and I would hate to lose him.
Thanx. H.
