What is wrong with my fish?

[ShanLPardy]

I have several Zebra Danios. One of them, a female, is larger than the others, and always looked a bit "bent" with a large belly. I treated the tank for bloat and anything else I could think of several months ago, and nothing changed. She always swam strongly, had a good appetite, and pretty much ruled the roost.
Today I see she's looking more "bent" than normal, and seems to be having some trouble swimming. She never looked this swollen. There's also the long, stringy poop she's trailing.
I tried to look up what it could be with no luck as she doesn't seem to have all the symptoms of one disease, but several of several dieases.
Advice needed!

Edit: the dirty looking glass is on the outside - some water spilled on the outside of the glass and I haven't cleaned it off yet.

Checked all parameters for Zebra Danios (pH, temp, etc, everything is fine)

30G tank
8 Zebra Danios
5 Cardinal Minnows
1 Clown Pleco
5 nerite snails

Sadly, this is not a healthy gravid female. She most likely as worms not bloat. The fact that she's defecating rules out bloat. In a separate hospital tank with no substrate, treat the fish with any med that contains Levamisole OR Fenbendazole. If the treatment is successful, you should see worms at the bottom of the tank within a couple of days. Because the worms will not be dead but just temporarily paralyzed and expelled, so not reuse any water or anything from the hospital tank until you have sterilized it/them.
In post #2 of my thread ( Quarantine tanks and Hospital tanks, are they really different? ) are instructions on setting up a proper hospital tank.

Hope this helps.
