I have done it and my observations are in a large tank it works as both species (kept in groups of 5 or more) tend to keep to themselves. Angelfish are generally more agressive than discus and can out compete the discus for food if the thank is too small. It is a debated question because the dynamic has to be balanced. If the tank is set up correctly so the Discus & Angelfish have an area of their own there is usually little interaction. So there is no set in stone answer and like all tanks it is a trial and error propasition what worked for one may be a disaster for another. A large tank set up correctly can and will work is my experiance. It would be interesting what others have tried and experianced.
A lot is often said about Discus picking up diseases from Angels.
Was this never an issue for you??




All my angels and discus started out very small so maybe that has something to do with it, they grew out together.
No never. I heard all of that too, Discus plague etc. I think that's one for mythbusters. Anytime you introduce fish together without proper QT there is a risk of disease transmission but no more than normal between Angelfish and Discus and any other fish.
You hear all sorts of horror stories though.
I plan on getting some Stendkers in about 6 weeks time.
There is an Angel in my tank, which I am quite happy to get rid of. But my 5 year old daughter considers it to be her fish. So I would not be popular if I had to move it on.
