I was at the grocery store today and stoped by the seafood counter to pick up some food for my trigger and my grouper. while I was looking I noticed a sign that said "Live Clams". After talking to the man behind the counter I discovered that they where saltwater and they where indeed live. I purchased one and brought it home as food for my trigger. As of right now the trigger has shown no intrest and the clam after a little digging is a cleaner clam theat is not photosynthetic as far as I can find. I plan to go back and purchase a few more tomorrow and see how they do. The kicker to the whole story is that I paid a whole 50 cents for this little guy. NO WAY you could get a cleaner clam for 50 cents at the LFS.
