Quick answer: there are about 6(or more) fish and most shrimp that will jump.
Ill let those who might know most of them tell you which they are.

Few fish are known jumpers. My 4 of my 7 endlers and one berried shrimp jumped so far. Well, it doesn't help when you have a bengal cat swatting at you, and sticking his paws in the water.

In short, all and any fish can jump.

Most folks would tell you angelfish aren't jumpers. I would answer to most folks that they are wrong. Spook a fish near the waterline and it becomes a candidate. Then there's the frenetic kamakazie fish that will do it because they can.........once.

Agree.. Any fish that's startled will jump. I have 6 tanks currently with no tops, have had them up for years, have lost maybe 3 fish to jumping and that was during a water change and I didn't notice them leap. Only thing I have ever lost out of tank on their own, was bamboo shrimp. Stupid creatures. Lol

I have 3 rimless/topless tanks with a variety of fish and the only thing I've had jump out of my tanks are shimp. Needless to say the shrimp tank has a sheet of glass over the top that is the same dimensions as the top so it has a nice sleek look to it.

Topless tanks are wonderful. I don't lose fish often but I've lost black neon tetras, bloodfin tetras, and killifish (obviously).

 

[scapegoat]

fish jump to get away from a perceived threat. My killi's jumped because the congo tetra are manic and bum rush anything they think has food, or is food. This caused a number of my killis to jump.

other than the killis, i haven't had a single jumper in the past few years w/ all open top tanks

 

[lamiskool]

even with rimless tanks you can buy tank clips which will hold up a glass lid. I will take a photo of them on my tank later tonight for you.

The only fish I ever lost to jumping was a betta and that tank had a cover. The fish was somehow able to find the one open area, a 1.5" X 2.5" slit for equipment, and bailed out that way.

this is interesting, thanks for your replies. I may look into the glass tops you cant see for my next tank then as I had a plan to have quite a small tank and have mainly shrimp
