The answer to your question is simple. I am not a discus keeper, but in this hobby for some time. Temperature of 26C for discus is too cold. discus require temperature around 30C. The main reson that not every plant is good for discus tank
is that most plants and discus require different temperature, plants don't like 30 degree.Next time before you'll get discus do some reserch on the net. Regards. misha
Hi,
I don't agree that the answer is simple.
Most answers are not. Most problems are multifaceted. For one who has never kept discus, i find your reasoning questionable. In fact so do others:
Below are the recommended temperatures for
Discus Aquarium Fish tanks:
Display – 27.5 to 29°C
Breeding – 30 to 33°C
Growing On – 29 to 31°C

My experience with water temps are the higher the temps the higher the discus metabolism and their growth rate.
Most folks don't know the difference in keeping "wild discus (Heckels) versus farm raised ones.
Most discus suffer from "stress", which weakens their immune system making them susceptible to disease and eventually death........indications are darking in color and clamping of fins, and loss of appetite..........
You never mentioned what tank mates they had, which is important...........for the stress factor
The following are the best tank mates:
14 different Tetras
Black Neon Tetras to Rummy Nose Tetras
The smaller Tetras will be eaten by the larger discus.
There are other fish compatible with discus, however, many believe they don't belong in a community tank, but a species only tank. There are signs to look for listed above.
Different fish have different requirements to survive and flourish. Discus need pristine water conditions, some claim low TDS, and very frequent water changes..........we do 50 % weekly......and they are fine (Our breeder J. Wattley does the same w/cs a week, on his planted tanks......)
Discus friendly plants:
Anubias
Vallisneria
Lily Bulbs
Water Oignon
rolata indica
java fern
Amazon Sword Plants- May not be included in theis list, however, they are part of the discus native habitat. Also, they favor rich substrate and prevent autotrophisation.
The above list is from Amano Discus Tanks List.
