Of all the different fish I have had, none have ever jumped unprovoked.
She lives alone, no fish near her, so no reason to jump to attack. Males live next door of each other, and if I didn't have lids on their tanks, they would and have jumped over to get the other guy.
Rainbow sharks, Tetra, Platy, Dojo and others, none of these fish have ever jumped out. I did have a Gourami jump out once, but that is because another fish was torturing it all over the tank. Main times to worry about a fish jumping is water changes, chemical shock, objects dropped into the tank and new light patterns.
