It has been a good while since I have kept odo's, but I treated them like beani. Very high aeration, if you think you have enough add more. Very staple water parameters, you could do this by not using gravel or using a very small layer of sand. Add salt to the water, I would say to point that you create quasi-brackish conditions. Feed vegetable based pellets that do not contain very high amounts of protein. The salt is important, Chris over at the cichlidscene raised a very large male odo. The whole time he added salt to the water. He stopped and the fish got sick, he was unable to save it. I have had similar things happen.
I have never heard of the 86 degree thing before. It seems irrational, higher temps equal higher metabolic rates which increases the amount of ammonia expelled from the fish. They also cause oxygen to be consumed at a higher rate which causes stress. Both are odo killers. When I kept haits (maybe 10 years ago) I kept the tanks at normal temps.
Just be careful to not overfeed. Once the digestive problems start, odo's get the long stringy feces. Once this happens it is all over.
