For over a year I kept about two dozen O. sayana in a small acquarium.
During normal times (daylight), they would be completely buried in the
sand with only their siphon visible.  Within a few seconds of dropping a
piece
of dead fresh shrimp in the acquarium, bedlam ensued.  The whole gaggle
suddenly popped up and began a frantic search for lunch.

Although they were fed various mollusks (Neverita duplicata, Donax
variabilis, or the catch of the day), they always showed more interest
in fresh shrimp than anything else.  Of course, I too would rather eat
a shrimp instead of a Neverita.

My acquarium specimens were still going strong after over a year and
half when the experiment was terminated.  Does anyone have any
information on the normal life span of this species?
