Did you put anything in your water to remove the chlorine and cholramine? Even if you aged your tank water, if your water system has chloramine in it, it will not go away by itself.

How long has the tank been running? If it's not been cycled, your fish could be the victims of an ammonia spike - drowned in their own urine, as it were. Check the ammonia, nitrite, and nitrate levels on the tank. If the first two aren't zero, then don't put any more fish in there until they are. If nitrate is over 40, then that needs to come down too.

Let see, what else could be the problem? Heavy metals - do you have carbon in your filter? has it been changed recently? If not, it may be leaching out all toxins it has absorbed. If that's not the deal, then you may need to get a water treatment that removes heavy metals (AmQuel+ is what I use.)

You don't by chance have any amphibians in that tank?

Most common livebearers have more problems not breeding than breeding. Basically, if you can keep them living, and you have male and female, then they will breed. Ideally, the ratio should be 1 male per 2-5 females (just like with people :twisted:). An 1 to 1 or worse ratio will have the female constantly pestered, likely to death. Also, if these are Sailfin mollies, then 10 gallons is way too small.

Something that just occurred to me - If these mollies are sailfins then they would benefit with 2 ppm of aquarium salt in the water, particularly if your water is soft. (I don't know off hand what that amounts to amount wise or specific gravity wise.). Mollies come from a very hard water environment - not quite Tanganyika, but their habitats sit on limestone shelves, and have a lot of calcium in the water.

If you don't have hard water, and you don't salt it, you can seriously shorten your fish's lifespan.

I think ask the seller what is the temp in their tank

mine was always about 80 to 82 degrees
remember to wash the surface bag and put the bag in your tank about 15 min then put the fish in the tank
and more important they can not give birth easily when the temp is so low . they if they were pregnant mabye they died for this.

if you have a good air pump as I did you can keep about 10 fish in 14 gallons tank ( I had 10 with about 120 fry )

and also remember the thing our friend said. 1 male and about 3 female
the live bearers like to live with other So try to keep a number of them
