My discus with other fish?

Yes same here, and i have a sand subtrate as these are large 5 inch discus, plants are no real but shhh, and they are with Keyhole cichlids that are peaceful.
 
You can't keep black and red phantom tetras with Discus? Why is that? I have seen it many times and I wouldn't see the problem. I've kept black and red phantom tetras along with Roberti tetras and find this hard to believe.

This is from the article I previously mentioned. Verbatium
"In addition, many small characins, like phantom tetras Megalamphodus spp. and flame tertas hyphessobrycon flammeus, simply can't take the heat, so they have to stay out of the upper-80's discus water."


It was quite a good article. It is in the October 2004 TFH magazine.
The article was called "Over 12 Terrific Tankmates For Your Discus"

Hope it answers your question.
 
How many discus can i keep in this setup, will they reach full size in here?

48x15x18
 
I find it really depends on the temperment of the discus. If your discus are very shy, it is best to keep them alone or else they will not get any food. On the other hand, the discus I currently keep have no trouble competing for food with any other fish. I used to keep them with wild altum angels and they had no trouble competing what so ever.
 
In a large tank I don't think a couple angels would be too much trouble for the discus. Angels do like to be the boss of the tank and will bully the discus during feeding time. I think your discus would be happiest with schools of tetras and hatchet fish. I have heard contradicting thingsabout angel diseases and discus. I suppose if there is such a thing, it would be in wild-caught angels. Most angels you guy are domestically bred, probably even locally. Altums are wild-caught so they'd probably be the bigger risk.
