@Newzooboy you're right. It seems as though the central tanks (the four on that big 'island' in the centre of the hall) are becoming more general without the Mediterranean speciality. One of them, for instance, had an Epaulette Sharks, Red Lionfish and Humpback Grouper. It just seemed odd to me for a crustacean with so short a lifespan to have been imported from so far, but whose to say it didn't come from another captive holder in Europe.
