I HAD a L. swalesi which jumped after about 6 months from
my previous 160 G open top reef
I did buy a pair of carmabi's last week here in the Netherlands (not from DD) and keep my tank protected from jumping... Hope to be able to take a picture of my pair soon! Saw them together last night for the first time

:inlove: In the picture you can see them in their bucket: I let them decide when to swim out, they took their time :wavehand:
I would definitely NOT keep Liopropoma's in an open top tank, sooner or later they will jump.
