Possible is not the same as good for the fish. In your other thread on the 33g tank with Discus
, I have outlined the problems that fish have when we try to force them into what is for them not natural, and this is another example. A "community" aquarium must be thought out in advance and all the fish selected must be compatible in every sense of the word, and this involves water parameters (hardness, pH and temperature), environment (the physical space in size and how it is aquascaped), filter flow, light, and last individual behaviours and traits of the species. Nature has programmed these fish, we cannot change them.
The problem with keeping fish at the high end of their temperature range is that is makes them work harder, and that uses more energy which tends to make them less "strong." Think of it in terms of you having to continually walk uphill; it just takes more energy than walking on level ground. And if this were to continue without break it would wear you down much faster. This is what the fish are going through. As another example, you know how you feel on a very hot day in the summer; you lack "energy," because of the increased heat. Same thing here. It is just wearing down the fish faster.
