Mollies are often raised in dirt ponds this makes them suseptable to
everything from parasitic worms, thru to piscine tb. Black mollies get
cancers and tumours.
They also benefit from added marine salt.
That said they are great fish and prolific in breeding once you nail a few
things.
First the diet, bloodworm is a good substitute for much of what they eat in
the wild. I have found spirulina flake to also be very good at getting
mollies to look their best.
With a good diet and a few feeds a day you should be able to bulk him back
up. Adding salt is harder if you have salt intolerant species in there like
corys?. Anyway a slight raise in tank water salt levels could help long
term.
As an actual med tho I think either a bath in full strength (same temp)
marine water or use a different method. I think the fluke meds you had
sounded ok, check the ingredients? if it's got (sp?!) praziquantral in it,
it should work. Consider trying to remove all the snails from tank as well.
If the fish dies try to get to it as quick as possible. Wear gloves, snip
the gill casing off and snip off a small piece of gill filiment. If you can
put that under a microscope or even a kick ass magnifying glass, or zoom in
on a 4 meg digital photo.... then you should be a able to see some wormy
things on the gills. Otherwise it's internal.
Or another angle 'metronidazole'... why do you have this and clout? has
tank had a 'bloat' wipe out before? It could be indeed a tb case. Does the
fish have any open unhealed wounds on it? any other fish with deformed
spines? If so don't be putting hands in water if you have any open
wounds.... fish sounds like somethings sapping it. In that case yes try
med the food with the metronidazole.
Anyway not trying ta make ya paranoid.
fluke tabs would prob work in a bath, even if ya just float an icecream
container half full of tank water with an airstone and dose of meds.
Plan B of course is just to 'remove' the fish from the tank. Can always get
another molly.

Yeah, i think you might have to use some kind of med for that, the link
i posted has all kinds of symptoms and diseases, it also has a link for
parasites, it is aimed towards goldfish, but goldfish and other fish get
a lot of the same disease, its one of the better web pages i have found
that talks about disease and symptoms & cures, i figured you might be
able to use it for at least that, I never had mollies before, luke tried
to get me to buy some the other day i think balloon ones (if that is
right) they are pretty, and i thought i could put them with the fancy
guppies, but i told him to wait till i found out a little more about
them, so he got another goldfish.

If you're interested in fish diseases, you might try getting a few books.
That website is pretty specific to pond goldfish and koi and is missing a
lot of diseases seen in tropicals. It also relies heavily on antibiotics
since you can inject them into koi and have less risk of making resistant
mycoplasma in your tank.

Did you read the FAQ? http://faq.thekrib.com

Yeah I have a lot of info stored on my computer for my other fish and
diseases they can get, since I just started with goldfish (well Luke did,
I'm just stuck doing the hard work) I thought that was a pretty good
sight. Read a book, did I mention I have a 6 year old, and two others that
are almost teens, Luke see's me as much as pick a book up he needs me
ASAP, unless of course its Harry potter, I just read the new one to him
and he rather enjoyed that. thats how i read now, eight find some thing he
likes or stay up all night....
