Does a Filamented Flasher Wrasse need sand?

[phenom5]

Quick question, does a Filamented Flasher Wrasse (Paracheilinus filamentosus) need a sand bed?

I don't think flasher's need sand, but I wanted to double check before I did anything rash.

Thanks

90% sure they don't, I think they sleep in a gunk-like cocoon.

I am 105% sure they do not. They form a cocoon to sleep.
