where in Detroit? on the NW side, there is Choice Aqarium. Off of Orchard Lake. It is in the Lovonia/Novi. Nice good of guys. Also try Fish Doctors. The original store in Ypsilanti (just East of Ann Arbor) is the best. There store in Canton, MI (275 & Ford Rd.) is decent too. West on Ford, then North. Sorry, the road name escapes me.
