The Fighting Conch is an excellent sand sifter for DSB tanks. It doesn't grow as fast as the Queen Conch, but each one needs two square feet of sandy surface area to get enough to eat. On occasion it will bury itself completely in the sand to where one eye stalk is all you can see, and may not resurface for weeks. This is normal, and perhaps that is its growing period. They jump quite high with a very powerful foot. The snout extends across sand and glass, but never on the rockwork.
