I've gotta ask: how do snails jump?
Yeah, yeah, I know: sloooooooowly...
I'm pretty cautious about covering all tanks. Aside from a few small fish like Swordtails, Tiger Barbs and Paradise Fish, I've lost very few to jumping. My two worst losses were my first Arowana, who jumped not only out of his tank but all the way down a flight of stairs from the second floor to the ground floor about 40 years ago, and a beautiful Red Wolffish just recently who managed to knock askew a lid weighted with a rock. Those two losses really stung me.
Now, if we were talking about reptile escapes, I would have stories...
Fish jump and die; you might find a desicated corpse at some time in the future, or if you are lucky you find a still-living fish and rescue it.
Reptiles are master escape artists, especially snakes, and can and do survive for long periods right under your nose. You haven't lived until you are sitting with your wife having dinner...and spot a 6- or 8-foot snake slithering across the floor behind her. The effort that must go into casually getting up and collecting the serpent without alerting the lady...wow...now that's living!
