I wonder what percentage of aquarium exhibits actually have signage that matches what's in the tanks. Of the places I've been I think Shedd did the best job.
@Gondwana Their coral reef tank, which has by far the most species, is 100% for everything I saw having a sign; I didn't see a few species there were signs for, an eel and two fishes. Asian River tank also all matched up. Looking through the signs again, there is one for northern puffer, but it doesn't look like this fish at all - which was the case for several of the coral reef fishes, as well.
