Help! Something Is Wrong With My Platy!

[Platygirl11]

Yesterday evening, when I went to bed, my orange platy was a picture of health. This morning, instead of being the first to rush up for food, as she usually is, she showed little to no interest in her flakes. I noticed that above her eyes she had a little ridge of tilted upward scales. Then I noticed That she had red spots all over her body, and larger ones on her tail and behind what I believe to be her lungs. Is it internal bleeding? She's bullied occasionally by the "alpha female" (the one who bullies everyone but not eccesively) but not to a very great extent, my red platy gets bullied more often, but with no biting.
Here are the unusual happenings recently:
•June 7- Orange platy (the sick one!) gave birth to four perfectly healthy fry
•June 7-Dwarf Gourami injured itself on ornament- ornament was removed
•June 8 to now- Treated with half doses of melafix

No other fish in the tank shows her symptoms, please help, the blotches are spreading!

Help?
EDIT:
She was swimming for a bit but now she's back to floating near the surface....

The dots don't show up on tape, but one half of her looks like a dalmation, only with orange with red spots.
Sorry for the bad description, but that's what she looks like!

How many gallons is the tank.
How many fish and which type.
How long has the tank been set up.
You have a nitrite reading so water change and increase aeration.

Red spots can be septicemia to parasites.
How big are the spots, are they the size of a pin head.
Any signs of flicking and rubbing or laboured breathing.
Any excess mucas on gills or body of fish.
Any bleeding beneath the skin.

 

[Platygirl11]

The tank is 10 gal.
4 platys, 1 male. 3 female, 1 dwarf gourami, 2 bronze corys
Set up for a few months now, about 3 1/2
This is going to sound horrible, but I'm nervous about putting my hands in the tank if amber (that's her name) may have parasites or worse...

They're bigger than a pinhead, but not all are the same size.
I don't see any flicking or rubbing, but she's hiding behind the filter.
No exess mucus.
I think the dot's might be bleeding beneath the skin.
Also, not all of the dots are dots, some are blotchy patterns which I think are bleeding, especially one behind what I believe to be her lungs right by her anal area.

Sounds like septicemia then.
You will need to add anti internal bacteria med by interpet to the tank.
Vad water quality can cause septicemia.

What do the fish gills look like, do they look red and inflamed.
Does the fish swim in a jerky movement.
Check her anus to see if its enlarged or red and inflamed.

Red spots on skin can be caused by:
Regarding the small red dot, small pinprick like haemorrhages (called petechiae) can be due to a local lesion, a generalised septicaemia or toxaemia caused by acute viral and bacterial infections.

 

[Platygirl11]

Her head looks sortof.... squashed... like someone smushed it out of proportion.
Her gills look red.
She doesn't swim jerkily, or much at all. she just hides behind the filter.
Anus is enlarged, almost looks like she's squared off, only she's thin....
All of her is oddly shaped. How could this happen so fast?

 

[WILDER]

How thin is she. Does her belly look sunken in.
What does it look like when she goes to the toilet.
Is he spine bending aswell.

Enlarged anus can be internal parasites.
Signs of internal parasites can be.
Long stringy white poo or clear mucas poo.
Fish will look skinny or bloated.
Sunken in belly.
Bent spine sometimes.
Enlarged anus or red inflamed anus.
Fish will somtimes swim on its side.
Internal parasites can cause bacterial infections.
Also they can cause brain damage, and the head region can look sunken in.
Red gils can be bad water quality, gill flukes, bacterial gillrot.

Also have to make sure its not flukes with having the red spots and red gills.
As fish can lose weight with flukes.
Sign of skin and gills flukes are.
Opaque body with excess slime.
Red inflamed gills or pale gills with excess slime. Or gills will look like there bleeding.
Flicking and rubbing.
Darting or erratic swimming.
Swimming in a jerky movement.
Weighloss.
Gasping at surface of tank or laboured breathing.
Spitting food out.
Sores on the body of the fish.
