Exploding Fish/Sick Mollies

[Carmen]

Firstly, my flatmate fished out a dead fish for me today and left it
in a jar for my inspection. Nice. It had a hole in its ventral side
about 3-4mm in diameter. Does anyone have any idea what happened?
Secondly, I found loads of fry this afternoon and I think they are
coming from the tank bicycle, the black molly. She is hiding on the
bottom of the tank looking thin and poorly and hasn't eaten today.
Should I be concerned or is she just recovering? The male looks really
ragged. His tail and fins have lost their colour and he has worn
patches on his surface. Otherwise he seems fine. Should I be worried
about him too?
I have increased the salt and everyone else seems fine. Any advise?

EMERGENCY
1. check the water parameters: pH, ammonia, nitrite, nitrates
2. do the fish physical
3. change some or all of the water, add 1 teaspoon salt per 5 gallons water
4. from the water parameters and physical decide on a course of action
5. if there is nothing specific, do the tub to tub method
