I personally think that the Ark Pet Shop in Merrillville, In is one of the best
around here. They
have a fairly nice selection of plants and fish. The are located at the
intersection of US 30 and
RT 55. Phone # 219 769 0661

Also Crystal Clear Aquarium has a nice selection of hard to find fish.. not so
much plants.
Located behind Schoops in Schererville, In. at the corner of Austin St. and US
30
