How high can fish jump?

[Green_Reefer]

How high can a fish jump above the water-line in a tank?

I have an in-wall display and I plan on making a three sided removable perimeter screen to stop fish from jumping. I was thinking 12" high would be good, should I make it higher? I will mostly be keeping 3" fish (wrasse, goby, firefin, assessor, anthias) in the tank with maybe one dwarf angel as my last fish. Currently I have 3 carpenter wrasse's that are doing great.

Thanks.

Difficult to predict. I would guess/think 24 inches should be ok. At least for the ones normally found in aquaria.

How deep is your tank? ie how much speed can they get up to before they break the surface.

21" tall, overall dimensions are 48x18x21. I can't see 24" jumpers even if they used the full length of the tank to build up speed.

Mine is 4in high and i've never lost one. I would guess as high as your longest fish.

Well, I have seen them hit 12 inches frequently. In my tank they bounce off the hood. But pay your money, take your chances.

I've seen anthias jump close to 2 feet high & they don't need a deep tank to do that.

Large fairy wrasses are very strong jumpers, I would think they could get 2 feet with out a hole lot of trouble. IMO

I've seen a diamond goby jump over 2ft up, and 6ft over, coming out of 8inches of water.
