You can, but you shouldn't. You can read about Discus in our fish profiles (click on the highlited word in blue). I can give you many reasons why this isn't a good idea but perhaps read the profile and come back with questions??

If you don't stand up for something you'll fall for anything...

Sure you can, but there are a lot of questions to go along with it. How big is a "baby"? Nickel-sized? Quarter-sized? Two inches? How long would you be keeping it in there? How long would it be before you set up a bigger tank for it? How often would you change the water? What else would be with it?

Lots of people grow out younger discus in smaller tanks because the water changes are easier and less wasteful (I'm doing it myself), but they do it with the intention of moving them to an appropriately-sized tank when they're ready. Since little discus need to eat 3-5 times a day you have to do lots of water changes, and it IS a heck of a lot easier when they're in a smaller tank. If that's your plan then yeah, you could have one in a 20 gallon for now. If you want to keep it in there permanently though, no way. I'd be planning on moving it at 3 inches if it was a normal tank with substrate, plants, other fish, etc.

Neons are not good with Discus, as they each require different water parameters/temps in order to thrive. Cardinal tetras work well with Discus.
Most plecos shouldn't be kept with Discus because there is always the possibilty of the pleco deciding to feed of the slime coat of your Discus. Heck, I even had some otos in my display tank that decided my female pigeonblood was a tasty free meal. The otos were removed and placed in another tank. My LFS guy had never heard of otos doing this and he's been in the business over 20+ years. I keep an ABN with my Discus and he's never bothered my Discus. Tankmates for Discus need to be chosen wisely.

Not to hijack, but now that you mention it I recently had an oto do the same to my red turq. I couldn't figure out what the heck the whitish patches in his slime coat were, and then I saw the oto try to attach itself to a cardinal and realized that he must be looking for slime at night. He was moved elsewhere and I replaced him with some mystery snails, which actually do a better job than he did anyways. Plus the discus absolutely love staring at them.

Otos being even a teeny bit aggressive?! are discus slime coats that tasty?

I don't know how tasty those slime coats are but it must be pretty darn good. Once the otos started this behavior they wouldn't stop. While it probably wasn't aggressive (just hungry otos) it was pretty freaky to see not one, but two, and sometimes even three otos going after my pigeon. This particular pigeon liked hanging amongst the hygro angustifolio, the exact same place that the otos preferred. She would flick them off, but Discus, being the drama queens that they are, don't deal with stress well. I knew the otos were really stressing her out. So, I painstakingly netted out each and every oto (I had to catch nine of those suckers) out of the display.

Ostara, due to our experiences maybe we need to make a note to the Discus profile: steer clear of otos!!

(not really hijacking since the thread is about Discus and the OP asked about Discus tankmates)
