I agree with the general consensus. It's not if, it's when. But yeah, fairies are more likely to jump, like Cody says. When my lineatus gets startled, it'll try to dart out of the tank. If I didn't have netting, he'd be on the floor dead by now and he's huge. The smaller wrasses, I never witnessed jumping, but it'll happen.
I don't think a screen frame looks bad on a rimless if you get precise measurements where the frame sits on the glass itself or the euro brace if your tank has it.
