I do understand where you're coming from, but I'm willing to withhold judgement for the time being. I haven't been to Petco in a very long time, probably 8 years, until pretty recently. The fish I got tended to sprout ich shortly after getting them home, or dying after a few days. I went in about a month ago, just to waste time while the wife and kids were doing some clothes shopping, and that Petco has undergone a *major* change. The fish section was enlarged, and the staff much more knowledgeable than I had previously experienced. I asked some questions I already knew the answers to, and some that I suspected the answers to (just logical assumptions that I hadn't had verified, but have had the answers verified by my preferred LFS), and received good answers. The fish and plants look healthier than they had in the past. I even overheard one of their sales reps refusing to sell fish to an aquarium newbie "because an already cycled tank is an easier transition for the fish, and both you and your fish will be happier for it" and gave instructions on a fishless cycle, and sent that customer home with tank fixings and test strips. That Petco, and another I searched out, don't seem to have a tank big enough for an arowana, but they have several tanks that should be reasonably suitable for juvenile discus as they are pretty tall. I'll wait and see before dubbing this a failed experiment in Petco stocking.
