We don't know what is meant by water is fine, so could you give some data please? Hardness and pH are important for livebearers; you can find the GH from your water supply people, and you should have a pH test kit. Then, have you tested for ammonia, nitrite and nitrate?

How long has this tank been running? From the symptoms I am thinking possibly high ammonia or nitrite, due to cycling; or low hardness and pH. Frayed fins can result from this, and remaining in the filter stream just prior to death suggests the fish is trying to get fresh water to avoid something toxic.

I don't see anything there. I did forget to ask the tank size. And normally how often are water changes done, and how much water? What water conditioner? And are any other substances going in the tank water besides the conditioner?

The tank is 100 L
We put tap safe in water and thats it WC about every 2 weeks with about 20 litres
Water looks great and clear thanks for the info but should i do more changes if this carrys on mate

A 100 litre tank is equivalent to around 26 gallons. Initially there were 4 molly and 9 guppy. The only thing i can see from all the data is still the effect of the initial cycling. The tank would only start to cycle when the fish went in, and this probably affected them. Molly as I mentioned are particularly sensitive to any form of nitrogen (ammonia, nitrite, even nitrate). Even though fish seem to survive the cycling, it can take a toll and weakens them considerably.

Water changes should be every week, without fail, and I would change about 1/3 of the tank. If the tap water hardness and pH is close to the aquarium's, this will be fine. Vacuum the substrate during each water change (assuming you don't have live plants, if yes, then you can leave the substrate).

If your tank is still doing its cycle I would do water changes every other day. To prevent poisoning from the cycle.
