The localy places know their stuff, which is good. The PetSmart I have has healthy tanks and fish, but they are about as dumb as bricks when it comes to the fish themselves. The Petco I have is the same as PetSmart, but there is one guy who seems to know what he's selling.
Walmart, lol! They had a longnosed gar who's head was bent at an exact right-angle there once, and I know a guy who went there and looked at it, played dumb, and asked the manager if that's how they naturally looked, and was told that they were supposed to look like that.

Why is Pets Plus infamous?
