how many silver arowanas can i put in my old 575 gallon koi pond? its 8'10"x4'9"x1'10" (LxWxH). My original plan was to put snakeheads but then i realize. they will be hard to see since the pond walls and floor is black. Anyway, im planning to put 4 silver aro. will they fit once they are all grown up? and arowanas can leap out of the water right? my pond has a 1 foot wall from the surface of the water. is that enough to prevent the silver aro from jumping out of the pond?
