was out in sterling heights on monday so i tried to hit some stores out that way. Bit of a let down, 2 of the stores had gone out of business, great lakes aquariums was closed (wtf who's closed sun, mon, tues, weds) and the last one had a mediocre list of fish. best pets on dequindre was the only one open and they had so few fish in there tanks not sure why and almost no plants.
Greatlakesaquariums when I went like last year there main thing is aquariums obviously but they had a few tanks of saltwater stuff. Best Pets everytime I go there sounds the same as you described. I'll have to check out and found out where Pet Vendor I'll have to stop in there.
