It really offends me when people say things like this. I work in the aquatics department at Petsmart and while I do agree that there are a couple of people working with me who don't know anything about fish (both are new employees) majority of those working in my department know a good deal about fish keeping.
And as for the fish being culls, impossible. Petsmart has there own fish breeders where they get only the best fish, not culls. The reason the fish are only a dollar is because, just like every other big name store, we are having a sale. Neon tetras, assorted platies, red minor tetras, and african dwarf frogs are also on sale for a dollar but only if you have a pet perks card. Please get your facts straight before you go about bashing something you know nothing about.
I'm curious as to where this petsmart is located, my petsmart doesn't even have rams right now.
