We bought a plecostmus from the Rockaway NY Petsmart. It died 2 days later.
I went to the store to get a replacement. They checked the water, and told us the alkaline levels were high, but that shouldn't affect the fish, so offered to give us a new one, but only told us then that there wasn't enough algae in the tank to support it. Then the manager, Chris, said they couldn't give us a replacement no matter what without a receipt.
My wife returned that same day with the receipt, and they continued to give us problems.
Mind you, this is for a $1.60 fish! Both my kids were crying at this point over the dead fish, but the manager, Chris, did his best to avoid us at all costs.
Most of the Plecostmus in the store died of starvation anyways, according to one of the staff.
Never buy from this store if you can help it! The fish are not well maintained and the staff know hardly anything about what they are selling.
