I had a pair for over 5yrs and one day for no reason the female jumped from my old solana. she was the dominate fish in the tank so nothing messed with her. normally they dont even go to the surface of the water, but for some reason she jumped. i wasnt home when she did so i lost her. so in 5yrs ive only had 1 jumper and always ran open top tanks. so i would think no.
