I subscribed to your thread just to see what answers you get. Two Turtles is the only decent store I know of in the Akron area. They're great but a tad pricey sometimes. ($5.99 for one cherry shrimp)
I go to Something Fishy by the Cleveland Zoo once in a great while. They specialize in Africans and that's all I've ever got there. They have other stuff too though. It's pretty far from me.
I'd definitely take a road trip if someone gives you some suggestions.
