Whitecloud with odd growth

[S-kate]

One of my white clouds has an odd growth on its abdomen. Its a round white bump. Also yesterday one of my Otos died and I'm thinking the two are connected. My perameters are:
0 ammonia
0 nitrite
0-5 nitrate
ph- 7.6

The rest of the fish seem fine, I'm going to try to get a picture with my roommates digital camera, they keep moving too fast to get a good one.

Edit:

Ok having trouble with the pics, and I have to go to a meeting. So more later.

So, any ideas?

I know it's hard to take pics of those things. Does it look like a big pimple?

I had some kind of internal parasite in my fish, and the pimple thing turned out to be a worm, which was really gross. It also killed my fish. As far as I know, the parasite didn't infect anything else.

Did you notice anything on the oto?

It does look like a big pimple. The oto looked normal, though he did seem a bit plumper than usual for a couple days. I didn't think it was a problem because otos are supposed to be a bit plump.

Ok I'm now noticing some dark spots on a few of the other white clouds. What is going on? One of the white clouds looks like he has a bite taken out of him. If this is worms how do I treat the tank? Will salt do it?

Edit: one of them is now floating. My poor little fish what is happening?

How long have you had the white clouds? The dark spots may just be from stress, but it's hard to tell. Is the gourami bothering them at all?

 

[S-kate]

I've had the whiteclouds for about a year, one is new and that was the one that died. the spots now look like little lines, I think they are worms.

The gourami nips occasionally and they nip him ocasionally. It is never a constant bullying though.
