phoenix tropical imo knows the most about fish out of all of the lfs i've been to in az. Charles is the person i aways talk to and he knows alot about fish. everyone worker in phoenix tropical has alot of tanks of their own. Charles has a pond with clown knives, silver arowana, peacock bass and other monsters, he also has alot of smaller tanks with different fish. the owner of the store has a huge 1000 gallon aquarium with monsters. the workers are aways friendly, and they have helped me with treatments when my fish get sick. they also know what they are talking about when you ask them questions about fish. for more community fish, you could go to fins and friends at 16th street and bethany home road. for more monster fish theres tropical treasures at 30 avenue and bell road (their tanks are overstocked, but they always have monsterfish)
