Fin rot?

I think that one of my longfinned zebra danios has fin rot. His tail looks like it is fraying, and there are splits in one of his fins. Does this sound like fin rot? If so, how should I treat it? If not, what else might it be?
Any information appreciated!

The other fish are 4 zebra danios, two guppies (one male one female) and one Bolivian Ram. I only got the ram a couple of days ago, and he/she goes nowhere near the danios. I have seen this particular danio nipping at the others, so I don't think he's being picked on...he's the largest of the bunch. All of the other fish appear just fine, although the ram is a little shy and stays mostly near the bottom of the tank (they're more bottom dwellers anyway, though, aren't they?).
I haven't tested ammonia, nitrite, and nitrate yet. Last I checked ammonia and nitrite were 0 and nitrate was between 10 and 20 (I think...either that or between 5 and 10).
I have not changed anything recently, other than water, and I added the ram and male guppy this Sunday. There was another ram, but I found it dead last night :(
I noticed a split in this danio's tail a while ago, but I thought it might just heal on its own.
I can try to get a picture, but probably will not be able to...the camera freaks out the fish, so they move away when I try to photograph them. Also, the danios don't stop moving long enough for me to focus.

For your camera: You need to use the action setting for danios....then get really....really...lucky.

How big is your tank with all these fish in it? Maybe an overcrowding issue? My guess though, is if this is one of those longfinned danios it may have ripped its fin on a decoration. Before doing much else you can add some garlic juice to the water and/or feed garlic juice soaked food for a while. It's supposed to help the natural immune system and allow them to repair their fins and such more quickly.

Random stocking concerns:
1. If you have the space you should add a couple more danios. They like to school in groups of 5 (some say 6) or more.
2. You have a male and female guppy in a tank together for longer than five minutes. Congratulations, she's pregnant. Now you should probably get another female guppy so the male doesn't pester her for nookie all the time while she's busy being pregnant. The general rule is 2-3 females to 1 male for livebearers.
3. How long has your tank been set up? The water parameters in your tank may not yet be stable enough to support rams.

The tank is a 20 gallon high, and it has been set up for over a year now...about one year 4 months.
So far the male guppy doesn't seem to pay much attention to the female. He swims up and down and side to side next to the glass a lot...I think he might be looking at his reflection! *SUPERSMIL He thinks he's handsome (which he is).

I have a random question, though. What should I feed my Bolivian ram? I feed flake to the rest of the fish but the ram doesn't come that close to the surface...sinking pellets, maybe?
