Took the kids to a public aquarium today and in one of the tanks they had oranges. Anybody know why? It was a saltwater tank with a variety of fish in it. I tried to take a pic but I was busy trying to herd cats so I could only get 1 pretty crappy one. I tried Google but couldn't find much. I did find one thread on here from 2010 that talks about an article that suggested oranges as food for tangs? I didn't see any tangs in the tank but it was pretty massive.
