I'm a bit panicked, please bear with me.

This is my first experience with a mass breakout of some kind of disease. I have no idea what it is, and it's too difficult to take pictures! I'll do my best to describe it.

I had a neon last week that had his head turn white. IT wasn't spots (like ich would be) it was just like his head turned white. He was dead the next morning, and his head looked like it had been nibbled on. I also had a deformed Zebra Danio that just died on Tuesday. He kind of grew a hump on it's back.

I just got home from work and took a look at my tank. I have 2 or 3 red-eyes with white patches on their back. I also have one red-eye with a growth over his eye. I have one neon that has a white spot on the back of his top fin.

Water Parameters:

Ammonia: 0
Nitrites: 0
Nitrates: 10
PH: 7.8

I just did a water change on Sunday night...about 50%, probably a little more. I don't want all my fish to die...any ideas? Please help!
 
I've had my zebras develop humps slowly over a span of time with extreme age... as for the other, it sounds like either you have an outbreak of fungus, or perhaps there's an aggressive fish in the tank? What in all are you keeping in there?

The only time I had a bunch of fish show up with white patches was when my brother put a red-tailed shark in with my docile little danios and tetras. It was biting chunks out of them!!

Are the white areas fluffy? Do they look fleshy? What about the paremeter around the white areas... is it white? Does it look raw or torn? Are the fish breathing/swimming/feeding normally?

My first instinct would be to add an antifungal medicine to the tank and see if it wipes out the problem... but I'm little more than an amatuer when it comes to diseases. I had very few of them in my 11 years with community tanks... but that's my two-cents. Fungus or aggressive fish attacks.
 
I only have one tank, and the fish are listed in my signature. There is no one that is anymore agressive than the other. As for the white patch, it's right behind the dorsal fin, and it looks like it could be fungus, but what about the eye growth and the spot on the neon?

I'm going out tomorrow to get a good hospital tank setup. I just don't know what I'm going to treat it with.
