After looking at all of your pics its no surprise he jumped out 5 Oscar's and a aro? Thats tank is way over stocked
In my experience aros and Oscars are not good match this is my experience I have three aros and not one of them jumps I have a 19 inch aro right now that I got at about 4 to 5 inche on may 25 2014 so less then a year. my aros do not jump and hit the lid I can touch my big one and he wont budge. Do they jump in the wild yes for food I feed them massivore pellets witch sink and they go right to the bottom to get them. Also allot of fish can grow 3 inches a month gars arapiamas aros and even some plecos I know this to be a fact becuz I have everyone of those fish I just mentioned and if fed everyday to there hearts content they can grow very quickly tank size playes a huge role in growth. My aros in my 450g gallon tank and will grow so much faster then somebody with a 100g or even a 200g u cant convince me other wise I have living proof.
