That is the problem with most pet stores.....they aren't concerned about the animal...only the profit. Pet stores sell hundreds of baby Iguanas every year with most buyers totally unaware of the large size they will eventually grow to. Same goes for fish, alligators, snakes, etc.
That's how to I feel when PetSmart sells a common pleco to someone with a 10gal!
I realize this is an old thread but in case anyone is still keeping tabs on it, a great aquatic store in NE Ohio is Aquatica in Valley City/Strongsville area. They have tons and tons of tanks. Salt and freshwater. Not tons of plants or shrimp but they've got fish out the wazoo. Even some frogs and salamanders. Check em out.
