The ethics of rimless tanks and fish jumping

Not trying to start a war but fish jump. Almost all species can jump out of a glass box. I can't count how many posts I've read where a hobbyist state that this or that fish jumped out of the tank and died as if that is some sort of surprise or could not be contemplated. It should not surprise anyone.

Put a lid on it. Your tank looking cool should not trump avoidable fish deaths

Agreed. At the very very least, don't gamble by putting known jumpers in a topless tank. I've done it in the past and been lucky, but I know better now and believe in this post. Only fish I lost to jumping was in QT when I forgot to put the screen cover back on. I feel really guilty when any fish dies in my care, knowing that it could have lived much longer in its original environment. If its something I know I could have prevented, especially with something as easy as a screen top, I feel really guilty...

A lot of these fish are pulled from their wide open ocean environments to live in our tanks. Its our responsibility to care for them in the best way we can.

Rimless are pretty, but I cover my tanks for both fish protection purposes and it dramatically reduces evaporation. It reduces light a bit, but I have to dial down my LED's anyways. With a larger tank auto topoffs negate the evaporation issue, but it gets less practical with smaller tanks.
Again, I love the look of rimless tanks, but I know a lot of rimless owners that as soon as company leaves and they are done impressing a cover goes over the tank.

New to the hobby. A rimless tank with a well made screen top is still better looking and more practical than a hood or cover. IMO there's no excuse for not having one for livestock safety.

99% of the fish sold in all pet stores are doomed, so an open tank owner is generally a better gamble then joe idiot buying a 6 line wrasse which you know will jump.

I think most open tank owners know better, but man it does suck when a fish you have had for 10 years decides to fly.

Best thing I ever did was cover my overflows with plexi cut to fit.

I personally have a RSR150 and love how it looks, but also care too much about losing my beloved fish that I purchased an artfully acrylic lid. Not super cheap, but doesn't take too much away from looks.

Honestly I've run open-top for over a decade, and the only time I ever had jumpers was in my first years of reefing. And I stopped having jumpers after I eliminated sources of aggression and introduced moonlight so the tank was never in "pitch black" darkness.

That said I do keep a lid on the tank of my 6-line i got a month ago, as a precaution, though i've yet to see any jumping tendencies from him.

I did this in order to prevent water spilling with an earthquake but Ive seen a wrasse of mine jumping out of the tank and this rim prevent him from going down the tank.
