What would be the possible ramifications for plants in growing in an aquarium with a high temperature, like in a discus tank etc', for a long period of time?

It will not help your fish vs 84F.
Mine Bred repeatedly at 82-84.

Most plants will be fine, something to think about, the warmer the water, the less gas it can and will hold(CO2, O2 etc).
So less O2 will be present in the tank.

Don't be so anal about Discus, they breed and do well in planted tanks, perhaps you will not get a full 10" fish or 40 fry vs 20 fry, but that's the not the point, a nice tank with the fish you want is.

Food is more important to breeding IME than pH/KH/Temp.

Thanks Tom. I wasn't referring to my discus but to my plants. The high temp. is for the discus. I was worried about my plants... :)

Personal experience indicates that quality plant growth occurs at lower temperatures in the region of 72-80. My tanks get into the high 80s in the summer and plants suffer (more than fish). Growth rate at the elevated temperature is fast, but tends to be stringy and colours are not as good.

That was the point, you do not need the higher temps for the fish.
They do fine for many years at 82-84F.
Gerenally, higher temps is not better, less O2 etc.

The more you push outside the limits of a system, the more changes for trouble.

Take care of the plants and the fish are quite happy.

As a point of reference my discus do quite well at 81F with a daily spike of 83F after the lights have bene out for a few hours. Plants seem to be doing quite well.
