when i had my aro he would try to jump out 2-3 times a day, it always scared me due to the loud crash of the lid jumping up a couple of inches, but he never got out. my bichir was about halfway out a tiny hole in the lid when i caught him being sneaky
I can honestly say......I dont know...............I had a n E - cat that dissapeared without a trace from my african cichlid tank............so I presume.....a jumper....and the cats had sushi????? but cant be for sure.....maybe the africans ganged up on him though???
