Just FYI, you can keep the turtles in the same pond as the cats,rays, and Gar. I made a simple wall of plexi glass that is 18" hignh that I haver around my pond to make sure my arapaima doesn't jump out. I haven't noticed my gars ever jump higher than an inch or 2. One of my gars is 14 years old and 4+nfeet long. The other is 5 years old 3+ feet. I think they are super easy to keep. I have had problems with arowanas jumping out..... sucks to find them on the ground. Good Luck and have FUN!
