Mine tried jumping out when I put him in the tank, and nearly did. But, live aquaria's water the fish was in was at 1.019.. My tank was at 1.026. So, I spent the half hour limit trying to acclimate him to 1.026 as quickly as possible without killing it. I had him up to 1.024 when the half hour timer ran out. So, I quickly changed out the last batch of water, got him up to 1.026. waited for another 5 minutes. Dumped him in, As soon as he was in he started darting for the surface. I then got him to stop darting and since then, he's just casually swam around the tank. Had him 2 weeks, he seems completely worry free and stress free now. Casually eats mysis or brine that floats by.
I have little doubt that one day something will spook him out of the tank... I've got a canopy on 3 sides of my tank and netting over the corner overflows....His only chance is to jump out the back.. I love the fish though, great markings, and has been very healthy.
