Sometimes it's the obvious that gets lost in the din.
It's not so much as "fish can and do jump", I learned this back when I was young and had a goldfish in a bowl or fishing for trout. Kinda obvious.
It's not the tank that's rimless, it's a chance one takes knowing all to well "it's bound to happen". Fish selection and compatibility does factor into this equation. Less aggression, less chance of jumping. Factoring in the environment surrounding the tank and how much activity that takes place close by to the tank, weights into the "startle effect". Notice I said "less". There is no guarantee that a fish wouldn't jump. None. Fish don't know the difference from a rimless from a canopy, from a lid, from a screen.....etc. I have very docile fish in my system. My grandkids make my wrasses "fly" in my canopy once in a blue moon! It's that once in a blue moon is all it takes. Obviously.
Respectfully, calling a tank manufacturer to inform them they should have a lid on their aquarium they sell is a moot point. Respectfully.
