Aquarium of the Pacific

Explorers Cove - Shark Lagoon - Adult Zebra Shark

I can also make out black-tipped reef sharks .....!
Any other species in the same tank?

I don't think that one in the background is a black-tipped reef - the body shape is different.

I'm not sure what the shark in the back was, but the aquarium had Bowmouth Guitarfish, Sawfish, Whitetip reef shark, zebra shark, nurse shark, Sand Tiger shark, Blacktip reef sharks, and a Reticulated Whiptail Ray. The website mentions a Sandbar shark, so maybe that the one in the back.

The shark in the upper left is a sand tiger shark and the one in the upper right is a sandbar shark. You can tell because of the large dorsal fin.
