thats why eels always jump. i had mine jump like 20 times before i realized that he was getting out right under the hang on filter. anyways i have had two tanks open top for a couple of years and only has one jump. I had a clown do it. But i also had a wrasse in there but he didnt jump he got stuck under a rock when he burrowed. I think it was a christmas wrasse. i would go for it. one bad thing is if you have a dog then some how there always is dog hair in my tank. !!!
i agree 10000000% with burdundi. If you have an open tank, any fish, save seahorses are capable of jumping, and it is likely you will have fish jerky sooner or later. as to which ones are more prone, wrasses are known for it, but dont think you'll be safe if you dont have a wrasse. Use caution.
I agree that all fish can be jumpers. I had most anything jump over the years. I don't think speed has anything to do with it. I had a mandarin goby jump (which isn't fast at all) but never a tang, which is very fast. I think it has to do with where they swim, their temperment (skittish fish are more prone to jumping while cool calm fish are less), and their tank mates. I think many jump cases occur when another fish chases the fish out of the tank.
The only fish which is "safe" from jumping are seahorses. Although it may not seem it, it is about swimming speed. Fish can swim faster than you think, especially when frightened. If you dont think so, try to catch one of your "slow" fish in your tank with a net. Seahorses cannot generate the speed to break from the water.
