fill your tank with some vampire plecs - they will eat any crustacean that contains meat... they ate all my round flat snails to extinction.... eat cone snails as well if theres no other food available.... just dont think they'd eat them to extinction though as cones are quite often buried deep in gravel....
but how did they get into your gravel in the first place... they werent created from stone were they !!! ???
Will they eat MTS Johnno?
