There's a place in Bridgview I stop by every now and then called Odd Lot Pet Shop. The place has been around forever and I bought my first fish there 21 years ago and it's still alive today. He does more than corals/ reef. He sells the typical pet store stuff so if you have dogs or cats you might like shopping there. It's in the mostly vacant strip at 77th and Harlem. He has some nice sized stuff and he's competitive with prices. I've also gotten some good deals on discounted stuff.
