dwarf cerith snail is another good algae eater for the aquarium.
They're herbivores that love hair and turf algae and will
effectively clean live rock more efficiently than regular sized snails.
Just like the larger cerith, they are among the hardiest snails to keep, because if they fall they
can easily right themselves before predation. These little snails
are commonly found at the low tide zone and spend part of their
time out of the water, so aquariums should have a rim or cover to
keep them inside as they will often perch above the water line.
Small sizes ranging from 1/4" - 1/2".
