My three boys and I were on our way home from the Cleveland zoo when we stopped at the steelyard commons petco, we noticed a large redtail catfish in they're turtle tank so I asked what the deal was. I was told he was left in a five gallon pale in front of the store, mind you it was -4º outside. So I decided to adopt him. My first plan was to build a cinder block pond but intex pools are so inexpensive. So here it is with rescued pacu. No fish purchased!
