Amphibians & Reptiles - North American River Bank Exhibit

What species do they have in here? Is it a primarily a turtle exhibit?

This exhibit holds:
Black Crappie
Golden Shiner
Green Sunfish
Gulf Coast Spiny Softshell
Longnose Gar
Pascagoula Map Turtle
Razor-backed Musk Turtle
River Cooter
Yellow-blotched Map Turtle

Here is my 2010 photo of what I'm fairly positive is the exact same tank:

The comments on my photo link make it seem as if there has been a dramatic alteration in the species that are now held in the exhibit. A lot has changed in 8 years!
