Not all fish species get along well in a tank together. Aggression and size can be intimidating, if not deadly, to the other inhabitants. Choose your fish wisely for a less stressful tank.
Here's a link to a chart for choosing ...

I've found that these go well with Discus:
German Blue Rams
Angels
Sterbai Cory's
Many of the tetras, but not neons
Brsitlenose Plecos
Pearl Gouramie's
I agree...all are mostly docile......at least when not looking to pair up...LOL...
Brochis Splenden will tolerate the warm temps with Discus. Believe me, they look good together.
I went back and looked this up.....

Common Names: Emerald catfish, common Brochis, emerald cory
Type Locality: Rio Tocantins, Brazil
Range: Amazon River Basin
Taxonomic Troubles: Originally described as Callichthys splendens. Has been known by a variety of names, including B. coeruleus, B. dipterus, Chaenothorax bicarinatus, Chaenothorax eigenmanni, and Corydoras semiscutatus.
Size: 8 cm (3 inches) TL.
Preferred Water Chemistry: Tropical freshwater; as with most fishes with large natural ranges, this species is quite adaptable to non-extreme water chemistries.
Difficulty: A very hardy species. Must be kept in schools.
Tank Setup: Most of the time a school of these catfish will be foraging in the substrate, so a lot of open area is important, but they like to occasionally rest in spaces under driftwood or rocks.
Feeding: Primarily a predator of small invertebrates. Will accept just about any food but is especially fond of live worms.
Breeding: Breeds in typical cory fashion, fastening eggs at the waterline. Young are not difficult to raise and go through a sequence of major changes in coloration, with the intermediate juvenile covered in dark spots and sporting red fins.
Description: At first glance this Brochis could be confused with the old favorite Corydoras aeneus, but besides growing larger, it has a larger dorsal fin and a more lyrate caudal, is more high-bodied, has a longer snout, and displays more intense and changeable coloration. Under ideal conditions this fish shines?hence the common name ?emerald.?
Notes: The intense, iridescent green of a Brochis splendens in good shape is best appreciated in person. Fortunately, keeping a school of these animals happy is not difficult?all they need is enough room, a suitable substrate for rooting around in, clean water, and a varied diet. Perpetually active, they are peaceful fish whose size nevertheless enables them to better tolerate other species that might harass their smaller cousins, the Corydoras. Although this species has been available in the hobby for a very long time, it has never gained the popularity it deserves.
Iridescent green, it says. That sounds lovely. I'd never even heard of them.
Would they be happy in a BB tank?
I doubt it...??...We got our four from Bob(Capt'n Bob) a few years back...they love the gravel and plants....Bob may chime in and correct me, if I'm wrong.
I doubt it, too. They'd go rummaging through the gravel in my potted plants and make a holy mess. Maybe one day I'll do a planted tank again. Every time I've done it I've regretted it. But given a little time, I get the urge again. Fool that I am, I feel the urge coming on.
I've seen where many people say angels and discus do not go together due to diseases or parasites (don't remember which one or if both) that angels carry. However I'd assume that truly healthy,clean angels would be fine with discus if kept in conditions conducive to the discus.
The question I would still have though is knowing that angels are insanely aggressive eaters and discus are more of a grazer, would feeding these guys be a bit difficult? Also, what ratio of angels to discus would work best? A group of discus to a couple or few angels....? That would seem to help with food distribution and satisfy the requirement of six discus being the recommended grouping for these fish.
I've seen some pretty aggressive discus, come chow time...they may look docile, but they can hold there own,,especially adult size.....I've seen discus get pretty brutal when pairing off too......disease?..heck either you have it, or you don't.....
I've never had a problem keeping the two together. Yes, the Discus like to peck around on the bottom in a leasurely fashion for their food, while the Angels attack it with a vengence. One way to get around it is to feed the Discus a sinking pellet and toss in flake for the Angels. Also, being a Discus person I don't mind over feeding because of all the WC I do.
I read the disease/parasite stuff when I first started out. I never bought into it. One thing I know is true is that Angels can carry some worms and hex and not show symptoms. They're just a tougher fish. If the Angels are harboring something you are unaware of, the Discus may pick it up and become symptomatic. But like Jon said, if the fish are clean, they're clean.

Had this tank for about a year. With the Angels and The Discus.
JR that was a nice looking tank
Thank ilroost That is a 180gal I will be setting that tank up soon
Nice, JR....good looking fish and tank...
Mike sent me a couple extra little 2" discus "to play with ". I have all 10 of my discus in a 90 gallon as I was originally planning on having only eight of them. There is a 20 long that I run under the 90 for extra water to handle the bioload. The one baby is growing fast the other is probably going to end up a cute little stunted blue fish. ::) I'd like to put a couple discus in with angels....oh what a conundrum. Lol.
As often as not, in a group of Discus their is one that is lowest in the pecking order. If you remove the smallest one they start dominating the next least agressive one. If I were you, I would wait until the Discus got older before I tossed a couple into an Angel tank. 10 full grown Discus are just fine in a 90.
You're right of course Liz. Thanks. I forgot about the pecking order issue. I'll leave things as is so I don't further upset things in the tank.
Makes sense...even if it's the little one's doing the harassment....groups of smaller fry can be a menace too..
They're Cichlids. It's their way...
