Polypterus in an open top tank - water level?

[Andri Pogo]

How high can they jump? Does anybody know?

I have a few small in an open top tank (old pic, trimac is gone...):

and was wondering IF i would add some of my bigger ones to the tank how low i should keep the water level from the top edge?
5"? more?

I would cover it, Polys can jump preety high. Wouldnt want to lose any? How big are the ones in there now?

that body starting just behind the gills is roughly 7/8 muscle

wow, ok i think ill cancel that idea
The ones in there now are only 4"

The 4 inchers will soon be big enough to jump out of that tank. I would find a way to cover it.

I had a foot long ropefish jump out of a container I had it in (I was moving it) and it had a 6" clearance between the water line and the lip of the container.

Not a good idea to leave the tank uncover. I lost a number of bichirs due to jumping out of tank. Best if you can fully cover it with a heavy cover as mesh cover is not able to hold them in.
