I would advise against this.
36 gallons is far too small to keep Discus as a community fish IMO.
As you suggested, the profiles here say this:
Discus get to be about 6 Inches, and because their almost circular looking that makes for quite a big fish.
Stocking wise, this tank can handle the bio load.
Space wise, the fish will get too big to keep in a community IMO. It could work, but I do think it is small. It's like the people who keep bettas in a 1 gallon tank *sigh*.
36 Bow front is 30.3" x 15.5" x 20.9. Basically not much bigger than my 29 gallon, which I would never dream of keeping Discus in. It is really only taller (and wider because of the bow) than my tank: 30-3/16"L x 12-1/2"W x 18-3/4"H
I really wish I could keep discus in my tank, but I really don't think they would be happy in that tiny space.
They should always be kept in a group of 5 or more except for breeding OR breeding pairs. They are schooling fish and are very social. This is the main reason most people keep at least 5-6 in a tank. They will be more active and happier. If you want to keep a nice school of discus I would suggest a 75 Gallon tank at the very least.
If you want the pair of breeding discus, you will be VERY limited on what you can keep with them in a tank that size. You would get away with a breeding pair but they would not be super happy in that small of a tank. If you want a pair, I would recommend getting a 40 Breeder which will give them more room to swim around. 36" x 18" x 16"
You get 6" longer of a tank, 3.5" deeper and its shorter. Discus live in shallow streams so they want wide long tanks. That way you stay with a small tank and you can still keep discus. Just a thought.
You will find that if you keep too few in too small of a space, they may get slightly aggressive with one another.
If you want 5-6 Discus I would get a 75-100 gallon at the least. That is my Opinion. Good Luck!
