i have a swimming pool about 3 ft high and 12 ft across . It has been awile since it was used so i figured all the chlorine was gone.. it was gong enough not to show up on the test kit so i threw my 2 pacus in there and they were gone about 2 hrs later when i checked on them.. that was awile ago.
I'm thinking "Where n the Hell did they go???" LOL
