I honestly have no clue. Though my first suspicions are either he's been mobbed by those little fish, or he got damaged some how. It also may be stress related.

EDIT: And like Quantum said it may be natural :3

Here's the Wetspot's auction for the zebra oto: AquaBid.com - Item # fwcatfishp1337815743 - Otocinclus cocoma Zebra/Tiger Oto WILD - Ends: Wed May 23 2012 - 06:29:03 PM CDT

the photo there shows a bit of color on the fish's head, may just be natural coloring that has become more apparent as the fish has settled, stressed fish usually pale in color

otos in general like to be kept in groups, so you may want to add more in time, more info: Otocinclus cocama (Zebra Otocinclus) — Seriously Fish

I concur with Quantum's ID on both fish, and I too suggest getting more of the zebra oto. This is mentioned in the SF link Quantum posted. And i agree that the colouration on the oto is likely natural.

Great. I'll look into getting another one or two Otos.

Is the bulb sufficient? What about the temperature?

I'd like to add some more fish too if you don't think I would be over stuffing the tank. What else would be good in addition to the fish I have?

I have harlequin rasboras (or however you spell it) in my 10 gallon tank and I have 8 which seems to be a good number. There could be a lot of aggression as you say perhaps from 2 males trying to be the alpha. This happens frequently with 2 males in my tank, you can notice this aggression between the two if you see their top fin go straighter or higher than normal and they tend to swim side by side in a little stand off (that's how I think of it). So yes, it could just be that a male is frightened of the alpha or a female that's being chased too much, however I have a different type of rasbora so it could be a different case altogether. That could be why he/she went away from the other 9 and unfortunately died, maybe just a bit too stressed out?

Sorry I can't answer any other questions.

I would get two more otos, a trio is minimum for shoaling fish.

Tube is fine. It needs replacing about every 12 months; it will still be lighting, but the intensity will be gone.

There is room for more fish, but stay with small (dwarf) species or things will look out of balance. Otos are not really substrate fish, so you could add a group of these, maybe some corys? A group of five would be nice. Several species are in our profiles. As for upper fish, check the dwarf species in the Cyprinids section of the profiles. There is a dwarf rainbow under the Athernids. And the Ember Tetra under characins. When checking these species, notice the water parameters as many are wild caught and specific.

just make sure you research the cories, many of the species would not do well in a small 10 gallon, but you could do some dwarf cories or I think salt and pepper ones stay small too, some will get as big as 3" so avoid the bigger ones.
