They are available at the marine scene off the toll road at 7100. What's that exit? The store is tucked into sunset shopping center, easy to miss it so I'd get driving directions first. It's directly on your left at the bottom of the hill practically at the turn. They said they are seasonal. They will tell you if they have them if you call first too. They had some red beauties when I got my beauty GBTA. It was the first shipment they'd had in awhile they said.
Good luck.
You might find the phone number under local marine aquariums listing ok?
