As I've typed above. I know all monster fish can jump out of the tank, the chances are just different for different species. So what fish, in your experiences, that would go out of their ways to find even the smallest escape routes to jump out and disappear? IMO, Silver Arowana, this species will go out of their ways to escape even if there's even a smallest gap. Cichlids, no, they'd often jump when they're being fed, or they see potential food at the edge of the tank, or they got chased by other fish, or if they weren't accustomed to their new surroundings and environment and felt unsafe. So I wouldn't say cichlids will go out of their ways to jump out of the tank. Then there are the likes of arowanas and snakeheads. So if there any other species like the 2 above, please tell me.
