OK, so I take 18 hours to get to follow up on my name being called out, and 6 pages of this thread develops. Is this all you guys do?!?!?! ;Hilarious;Hilarious;Hilarious
@sfin52, you are absolutely right! I tried them a couple of times (2 different tanks). They only bury themselves in the sand and over a few day die off. They live by the hundreds or even by the thousands at the surf/beach interface. But only end up completely underwater for 2 to 4 hours at a time during high tide.
They are very pretty and I wish they could work... but they are a no go except as food for crabs and they end up as empty shells in the sand.
I have found a small clam that also bury themselves in the sand that does survive long term in the tank. There are actually several variations of Venus Clams that inhabit Florida waters and survive in captivity.
