Hard stocking this smaller 28 gallon tank
 
I'm very new and have sort of gone about this the wrong way, but this is what I have thus far:

5 Black Neon Tetras
5 Male Guppies
2 Male Swordtails

I received bad advice from a PetsMart kid about the 2 male Swords, but I have them now and they are reasonably coexisting.

I've got room for 1-4 more fish, judging from watching my fish behave and interact. I've been directed to stay away from Mollies (aggression) and Platys (will mate with Swords and I don't want babies). I could add to my schools, but they seem content and I'd like a little more diversity. I thought maybe a single Gourami. Any other ideas to add to a friendly, beginner, community tank?

Thank you,

Zambize

Zambize,
How large is your tank? How is it set up? What are your water parameters? PH, temp, hardness, ammonia - nitrite-nitrate. What are you feeding your fish, and how often?
That information will determine what you can keep, if any.
I'd be glad to help you, but without that information, its a shot in the dark.

Oh, water is very hard, it's the highest on the chart. Local water...
I feed whatever my fish need but right now the current fish are enjoying a varied diet of:

Staple: Fish flakes + Veggie Flakes
Add one of these every few days: Frozen bloodworms, frozen brine shrimp, freeze-dried brine shrimp, Tetra Bites

They like the bloodworms and flakes best.

zambize,

You should have NO nitrite in your tank, as its highly toxic to fish. The presence of the nitrite indicates your aquarium isn't completely cycled. Ammonia and Nitrite must be dead zero 24/7/365. You don't have much Nitrate as your bioload is fairly light.
Your pH and hardness is OK for the swords and guppies, not so much the soft water tetras, which do best in pH 6.8 water with far lower hardness. You could easily double or triple your school of black neons in a tank your size. Tetras do and live best in schools of six or more. They'll be a much better display in a larger group.
You've been fortunate thus far, as a Nitrite reading like that usually means dead fish.
How often do you do partial water changes and how much per change? You should do no more than 20 percent a week. The new water should be the exact same temperature and water character as that already in the tank. A difference of even a few degrees of temperature can bring on a bout with the dreaded Ich.
I would assume you dechlorinate your water change water?
You should feed your fish small meals; no more than they can finish in a minute, three or four times a day. MUCH better than one large meal. Our aquarium fish are nibblers, that is, they eat when food is available all day. Varying the menu for each feeding is a good idea. Also, you can add New Life Spectrum pellets to the menu. An excellent food. That brand and Hikari are perhaps the best out there for fish food. Hikari micro-pellets would be perfect for your tetras.
Like people, the more variety in the diet the better the fish (and better the person).

With your extremely high nitrite, its time to do a large water change and get it below 0.25ppm. I know you just got some different advice but water changes are your friend. Properly dechlorinated, the new water will dilute the poison you have in your water to where the fish you have now can thrive. Do not add any more fish until the nitrite stays at 0 by itself.
As far as feeding, I might agree with Dave66 normally but right now you have a problem with too much nitrogen in the tank. Since it comes from what goes through the fish, it would be best to feed very little for a while until the nitrites start coming down. That means that you don't starve the fish but they need to be hungry when you stop, not fully satisfied. That way you won't build the level back up by the next day with partially processed nitrogen.
