Discus And Platinum Angelfish

I have 2 platinum angelfish about 3"-3 1/2" that have been in my tank for a while and are not aggressive at all so far.
Tank is fully cycled and is 37 gallons 30 in L x 12 in W x 22 in H .
I have 2 Gold Gourami's which can be relocated to another tank if need to get discus in my tank. but I am looking to get some discus.
My question is can I get any discus for my tank. and if possible how many should I get and how many water changes are required for them.
I can do as many water changes as they need. I have seen other forums of angelfish being to aggressive for discus to eat but my angelfish are not too aggressive when they eat they seem to be a little bit more passive than the gold gourami's when feeding.
I have also seen posts of angelfish having diseases that discus can get from them that don't affect the angelfish. but I can treat them for parasites and disease before putting the discus in if needed. My tank has plants and places for fish to hide.
PLease just let me know if I can keep discus in my tank with angelfish even if it is just 2 discus. I am willing to buy another tank to separate them when breeding. but I would like to keep them together when not breeding.
Thank you

 

Hello!
I am sorry to tell you but you can not keep Discus in a 37 gallon.

 

Especially with the two angelfish. You don't have enough room for anymore big fish.

 

Discus grow very large, and are very demanding about water quality. I would not keep them in less than a 75 gallon, and even that would be a lot of water changing work.

 

Ok thanks
