If any aquarium store in Phoenix deserves 5 stars, its this place. This place knows what they're doing. Take it from someone who worked at one of the largest aquarium stores in the country while in high school and has kept literally hundreds of fish.
Store is clean, great selection of corals, tech savvy prices on tablets. The employees are all VERY well versed and know their stuff. The display tanks hold things I've never seen in 30+ years in the aquarium hobby. Ribbon eel anyone? Sharks, eels....you name it.
The only small quip is their saltwater fish selection could be a little better/more diverse. Other than that, just an elite level well done store. Make the drive and pay them a visit!
