The difference is that my ponds are indoors. It still gets hot in the summer and cold in the winter, but much more mild. It might get into the 80s in the summer instead of over 100 and the winter might dip below 50 every once in a while.
There are also no visitors indoors. There are no coons, cats, bullfrogs, turtles, herons, or jerks in general.
I'm willing to bet if you put those chubs in a big tank with plenty of vegetation that none of them would have jumped out LOL.
Also, if you lost all of your fatheads in one night I have to assume that you have a huge problem with cover and structure. Even when I dump a dozen fatheads into my Oscar tank some of them live for a few days hiding out in the artificial plants or the stones.
