I have seen aros breaking weighted glass covering the tanks. They are jumpers. Leave no opening on top, however small.
It will always be a question of luck and of not spooking the aro.

Even if the lid is airtight (which is nearly impossible) oxygen still enters the water thru bubbles, sumps, etc.


Seems like some kind of DIY mesh/net would be smart, then the aro can't hurt itself on the lid or canopy and if properly attached there is no way it could jump out!

You guys, are scaring me! I have a 28" silver arowana and I am afraid this day will come. I cover my tank with a drizzle filter which is close to 50 lbs with water. This however does not cover the entire top, perhaps 30% is still open which I use for maintenance and feeding. I have prepared a metal screen to be put on top of my tank and now it seems I need to work with that one to avert a likely tragedy.

To OP, sorry for your loss. 20" of an arowana is too much of a loss.
 
I've always been told you cannot competely cover an entire tank with glass/ or whatever covers you've got on your tank as no air will escape.. When I bought my previously owned tank they had glass over the top, I have since cut out pieces of quarter inch thick plexy glass to fit into the sections of my tank, with about a 2" gap on the back of two of the three peices to make room for my two aquaclear 110's. Before I purchase an arrowana I want to seal off the small open areas next to my filters. The rectangular sections are about 2" wide by 6" long.. but I'm not sure if I should completely cover those excess areas with extra peices of plexy glass, or possibly some sort of mesh/netting material to let some air escape.. what do you guys recommend?

dont cover all with plexiglass ... some net should enough to cover :)

I think that's probably what I will do is use some sort of mesh/netting material. Just need to figure out how I can get it tightly secured incase the arowana decides to go crazy and jump into the netting.
 
Thanks for all the replies guys. I miss him terrably. It just sucks so much aspecially since i know they are jumpers and i took all the precautions i could think of. The tank is sealed and weighted all the way around. It is a total mystery how he got out. The lids were even closed and nothing disterbed on top of tank when we found him.
 
There is a good reason their nickname is "water monkey".

Have you ever seen videos of arowana in the wild? They leap out of the water to catch insects that walk on branches a few feet above the water in the Amazonia flood plains during the rainy season.

Watch this National Geographic documentary its actually kinda cool.

These guys can catch some massive air time. They are built to jump.

This is a good video too to see some sweet arowana hang time:
