I have an 85 gal total with a Royal Gramma, Melanarus Wrasse, 2 T/P Clowns, Fire Fish and a Midas Blenny. I want my last fish for this tank to be a bottom dweller, either a sand sifting fish or one that stays near the sand. I know it's dependent on the individual fish, but I have that sugar fine sand and corals on the SB, I'd rather not have to clean up after a messy sifter every day.
