Hi, since we all know that all fish can jump out. Most fish don't just jump out, they rarely do without a reason. For example, I don't think my cichlids like to jump out, they rarely do, but they will jump on 3 conditions. First, whenever I changed my water for 30% or more than that. Second, whenever I completely rearranged everything inside. Third, whenever there are bugs/insects or other potential preys on the edge. Most fish I've owned don't jump if they're used to the environment. My pacu and giant gourami don't, my cichlids almost never jump if I don't change anything. While most fish jump for reasons. There are several species that are known jumpers that like to jump for the sake of it, and has much higher chance of jumping out than most fish, that includes all the snakeheads and arowanas. There are also escape artists who like to crawl out like eels or lungfish. So I wanna know if there are any other species that are prone to jumping or escaping as much as the 2 mentioned above? If so, can you guys tell me if there are more? Also I'd appreciate if you guys can also tell me some fish that won't jump, or won't jump just for the sake of jumping(such as Datnoids or golden dorado cuz my golden dorado never jump, but it jumped once after I changed 50% of water.)
What fish are known jumpers or escape artists!?!?

I’ve done 75% weekly water changes in all my cichlid tanks for years. Never noticed clean water or the process to cause jumping, though all my tanks are well covered 
The only time my fish have jumped out has been when they were being chased by another fish. I've also heard of fish jumping out when the water is filthy or has a toxin in it.
I can confirm the latter part. A lot of fish will jump in desperation for better water. Some time ago I dealt with a wine barrel pond (bad idea, don't do it unless you have the patience to remove all residue in the wood) and all the fish ended up drying outside. And in my beginning days, when I had ammonia in my tank due bad decisions, you could hear the fish hit the cover where the water came in, trying to jump "upstream".
Some bichirs, especially senegal, really like to escape aswell and can jump suprisingly high.

I had that experience with bichir first handed, it never jump, until I changed 80% of water...
Yep, they'll jump out if they're chased(Never happen to me though.) My fish(don't include arowana and snakehead) never jump unless I just changed lots of water or rearranged their environment. New fish tend to jump also. They also tend to jump out if the water is too shallow(My black shark did jump once when I was draining the water out.)
