They are located on the Live Plant End-cap. They are $7.99 and we carry 7 different varieties depending on store. If i can recommend something to people, call your local Petsmart and ask when they get their fish shipment. Plants come in this shipment also. So for us in South Charlotte, it's Wednesday. We only stock 2-4 of each SKU at a time, so if you see the inventory getting low, then next fish shipment, snag some new healthy plants!
Also if you tell the manager on duty that the plants are dead and need to be thrown away and taken out of inventory, they will do so. Sometimes associates don't know when a plant is dead, but we sure do!
Does every petsmart carry them?
