I've seen various compatible fish for discus such as some of the tetras, but wondered if Rainbowfish would be compatible? I presume they are too active but thought I'd check to see if anyone has tried that combination successfully.
Well there are some basis to that argument, but there are indeed fish that can be safely kept with adult Discus.I've always heard that Discus thrive the best in a species only tank.

Some of the issues/reasons are:
1) Discus require a much higher temperature range that would be detrimental to many other fish.
2) Discus are "grazing" fish which means while they prefer to take their time on a meal, other fish may quickly consume all the food. Should be less of an issue for fully grown adults.
3) Discus can in fact grow rather large (8-10 inches), and while not known for being extremely predatory may eat smaller fish such as neon tetras.
4) The slime coat produced by Discus can attract unwanted attention from some species of fish who will attempt to eat the slime coat off the Discus' body. There are reported incidents of Otos attaching themselves to the side of a Discus for example.
