Like a lot of people have said, sand sifting starfish and conchs. I have 3 of each in my 150 gallon. They do a great jobI have a 100g 6 foot tank with about a 1.5 inch sand bed.
I would like to know everyones opinion on what I should use for best possible sand cleaning.
snails? stars? anything else?
I have a strawberry conch and a half dozen nassarius snails already.
