As a PetCo, they have their issues with limited and substandard stock, bettas in cups, and non-aquatic aquarium plants. That said, those of the staff that know their fish really do know their fish (and those who don't don't pretend to.) Prices are OK. I've seen some ick in their tanks, but they jump on it when it's there. All in all, and above average Petco - one I don't mind shopping at, and super convenient to me.

Brand new store. Manager is super nice (Got to shop before they officially opened) - some of the staff is nice & know what they're about - some not so much. 2 week guarantee. Same problems as any other petsmart vis selection, but they do keep some interesting critters (Leopard Ctenos, Dwarf Puffers, Violet Gobies, Botia Kubotai). Minimal number of deaders for a chain store. Excellent solution to housing bettas - long tanks, 6x6" cross section, with slotted dividers, hooked into the general filtration system.

I really like this store. The prices are reasonable for stock (sometimes excellent), not outrageous for equipment. Good selection of live and frozen foods. Number of tanks on par with a Petco, but the stock is turned over relatively quickly, and is often interesting. Some of the more interesting ones: Panda & Pygmy Cories, true SAEs, Sparkling Gouramis, Marine Bettas, Halfmoon and Delta Bettas (in cups, more's the pity). Fair plant selection - frequently changing. MTS $1 for 10. The Manager and Owner is a really good guy. The only points against: 2 day guarantee on fish only and I have gotten neons with NTD there. They have a second storefront just for tanks, stands, and driftwood.

Gigantic store, an old supermarket, with half given over to aisles of tanks. Huge selection of fish, tanks, decor, chemicals, equipment, the whole shebang. Saltwater selection is much smaller. Cleanliness is generally good, but they do get some algae problems from time to time. Excellent plant selection (if sometimes not in great shape). Staff is either friendly OR knowledgeable, rarely both, and it varies a lot. Prices are neither more nor less than what the market will bear, with occasional bargains.

I wouldn't shop here as a matter of principle if I had principles. They carry injection dyed fish, and sell dogs. That said, they have an astounding selection for the small number of tanks they have (arowana, motoro, whiptail plecos), and the best driftwood prices this side of the beach. Also a heck of a plant selection, given the the number of tanks. Because of the small number of tanks, though, there is a lot of crowding, and inappropriate cohabitation (puffers w/ long finned tetras). I wouldn't be tempted to Quarantine less than a month. My estimate of the guy who runs the fish section is that he really knows his stuff, and does his best with the space he has and the dictata of a small chain pushing to be large.

To the plus - this store has some of the healthiest, best looking fish out there. Good selection of tropical freshwater, equally large selection of saltwater and coolwater/pond fish. OK plant & equipment selection. To the minus - you pay for it. Everything costs more here. Staff is knowlegeable but not particularly friendly (not unfriendly either, though.)

Big store, great fish selection (OK equipment selection), good plant selection. Nearly ideal staff - patient, knowledgeable, and friendly - with both plant and pleco experts. 500 gallon display tank with an Arapima. Prices are good, and sales are better. Highly recommended. Wish it weren't such a pain in the butt for me to get to.
