has anyone had any experiance with these guys? good or bad for a reef tank?
Olives (Oliva sayana in this case) are predatory within the sandbed. They will primarily consume other gastropods (bivalves mostly) and worms I believe. Once done, they usually die. They are of no benefit to the tank.whitetiprs said:well I know that they are predators but I do not think that they move off the sand bed. so they might be good as sand stiffters.
Much better choice but you'll find nassarius are also a good choice.what about conchs? are they good?
