No problem, I've found I love the little catfish. I wouldn't worry about the mess too much, as the lone fish in the tank its unlikely he can finish even the little food you're offering him. Once more fish go in the tank, including some more corys, the mess won't be as bad.

1/16 NH3-0ppm NO2-5.0 NO3-7
No water change

1/18 NH3-0ppm NO2-1.0 NO3-5

1/20 NH3-0ppm NO2-0.25-0.5 NO3-5

Am I there yet or do I need to wait a little longer???????????

You're not there yet. A cycled tank has 0 ppm ammonia, 0 ppm nitrite, and nitrate > 0. I'd wait for the cycle to finish before adding anything new. Once you're cycled your tank will be in very good shape for the fish, until it is you're going to be on a razors edge the whole time. The good news is the cycle should be finished soon.

Ok... Patiently!!! waiting. lol

Should I keep changing water at this point or let it balance intself out? If so, what % water change do you reccommend?

Keep changing it. You've got fish in there and you need to watch out for their health. Nitrite is as dangerous as ammonia for them.

What % is really something only you can answer. Once the tank is cycled you want to change enough so that your nitrates don't rise above 40ppm. Changing more isn't a problem. Better to change water than not to change. Personally on both my tanks I change 30% a week. This is overkill as I've never seen over 10ppm nitrates in my 48 gallon or in my Eclipse. It's a good number for me on both counts as that's pretty close to how much I pull out just vacuuming the tanks. I wouldn't change more than 50% at a time though. If you need more than that change it more often.

I just tested the water (1/23) and 0ppm across the board!!!!!

I am thinking of getting a school of small fish tomorrow to add to the tank. I like the cory, but I don't think I am going to add any more, unless it becomes an issue.

Possible tank stock: (open to suggestio)
1 cory cat
5-6 red eye tetras, cardinal tetras, neon tetras, red zebra danios (if I can find them, supposed to glow in the dark!)
1-3 larger fish that are cool looking??????? would some angel fish fit in??

If the balanced cycling is recent I'd advise you to wait maybe a week before adding any fish! I added my cories too quickly in my 10g after I saw the cycling was done, and it really punched the newly born bacterias hard, it got all out of whack and it's still recovering!

Even though I cycled with a fish and introduce them slowly you think I still need to wait? I never saw a huge spike in Nitrate, never got greater than 10ppm, and it brought itself right back down to 0 without a water change. From what I have read the Nitrate usually jumps after the ammonia and nitrite drop to 0, requiring a large water change. This didn't happen in my tank........

I wouldn't worry too much about it. My tank has never had high nitrates. I can't get it over 10ppm even if I do nothing to the tank, no cleaning, no water changes, nothing and the nitrate is still low.

Look at it this way, you've got one fish in the tank right now. You have enough bacteria to support a single fish. The most I'd add next would be a single fish. Personally I'd add another cory of the exact same type as the one you've got. They're schooling fish, since you just used the guy to cycle with reward him with a buddy. Monitor the water and if in a week you're still at 0/0/X go ahead and add a third single fish. You guessed my recommendation, a third cory. Again, wait a week and if you're still at 0/0/X then things open up. You'll have three decent sized fish in the tank along with the bacteria to support them.

At that point you can consider adding in other fish. Me, I like neon or cardinal tetras. They have a low bioload so I wouldn't worry about adding 6 or either to the tank. Just keep an eye on your nitrogenous substance levels and make sure you don't set off a mini-cycle. A mini-cycle will be unlikely after the first fish addition. At that point you'll have a good sized bacteria colony that can grow quickly to accomdate new fish. Wait at least a week between additions and keep an eye on your levels and you should be just fine.

Angels will get too large for the tank. Your stocking list looks good, but I would seriously consider adding more cories. They are schooling fish and really need the comfort and security a school provides. Plus, having a group of them will really show off their interesting behaviors.

As for centerpiece fish:
-Smaller gouramis like dwarf gouramis (only get one as they will fight among themselves)
-Dwarf cichlids like kribensis, rams, apistogramma, nannacara
-Slightly larger cichlids like keyholes
-Maybe some big male swordtails
