Hello, I had 2 angel fish, 3 neon tetras, 3 sword fish, 2 bala sharks and a guppy separated in compartment. They lived together happily for 3 months and got food every day.
One day I got two silver mollies and suddently, one by one, fish started to die first the neon disapeared, then the sword fish died, then the angel fish died, one each day. To the point that there were only the 2 bala shark and the 2 mollies left and the guppy (pregnant) in the compartment. One day, the guppy was also gone from the compartment, like magic, I could never find the body. next day the bala shark jumped inside the compartment net.
who is the killer?

tikitiki may be correct. This may be a coincidence. If, you have not been doing regular water changes the ammonia and PH could be off, normally PH will go more Acid and can be neutralized slowly with Baking Soda (NOT Baking Powder). Size of tank will determine how much soda to add per day, so, we would need that information to help. When you bought the new fish the water may have been going bad and it seemed the new fish were your killers, when it was the water, you just bought the fish at that time, coincidence. Get a small jar like baby food or a little jelly jar, bigger if that all you have and fill about half way with water from your tank and take to your pet shop, most will check it for free, call around. I know Petco and PetSmart do. They can tell you what to do.
Sometimes a fish can jump out of the tank and just dry up on the floor never being found.
If, you have an aggressive fish you will usually notice it by the tail fins of other fish being torn or shredded before the fish killed.
IF, you find your PH is Acid, and you have some Baking Soda at home, e-mail me through here and I tell you how to use it, much cheaper. There is a way to adjust for the other direction too that cheap, but, I would bet money it be too Acid before it too Alkaline.

The larger male sailfin, and sailfin hybrids can get mildly aggressive, but generally they just chase a fish around the tank a bit. It's a territorial thing not a eat othet fish thing. Like most fish they'll eat any fish that can fit in their mouth, but a guppy is just too big.
Bala sharks are well known for being far more predatory than molly. That said like molly they've got a rep as a peaceful tank mates until they reach the size their tank mate fit in their mouths.
PS- You would happen to have a bottom feeder in this tank? Many catfish are predatory. As are chinese algae eaters as they get older. Pleco, and most bottom dwellers will happily eat dead fish.

Mollies do and will eat their fry though. They are one of the few fish that can go from fresh to full salt. Neat fish, never seen any real aggression, cannot remember anyway. I had some in with seahorses to produce fry treats for them. They never bothered the seahorses.
Is your tank new? Mollies are VERY hearty and can typically live through cycling a tank. If your tank is new and not cycled that could be your prob. Check for ammonia and nitrites.
The cycle starts with elevated ammonia the breakdown of that is nitrites and the breakdown of nitrites is nitrates, water changes takes care of that, The first 2 are deadly. I always recommend using a piece of shrimp or something to get the cycle started. Once nitrites drop after a few weeks your tank is ready for fish, add slowly so you do not cycle your tank some.

Generally mollies are pretty peaceful. I'd say get a test kit and check your water parameters for ammonia or nitrite(both should be 0) or even high nitrates(should be under 20). How often do you do water changes and what's the tank size? If it's anything under a 55 gallon, and you don't do at least bi-weekly water changes, I'd bet that's your problem.
