I think a sandbed, even a thin one is nessesary for the physcological well being of fish. every one of my fish has an interaction with the sand bed. my wrasse sleeps in it and hunts food out of it, my goby sifts it, my angel and tang suck whatever algae there is on it. Im probaly wrong on this but I would never go bare bottom.
just a country boys opinion
