Agree most sales associate's in the aquatics department at Petsmart, Petco, and Petsuppliesplus are not very knowledgeable but tbh most are placed in the department and learn from whom ever is there before them even if they don't have a clue. Those stores are focused on sales of other products other than fish believe me I worked for one of them and would smh everyday from what I heard from fish sales associate's.
