yes they do give birth, they look massive when heavily preganant.
1) what is your water temperature?
2) what else do you have in the tank?
3) what size is the tank?
4) what do you feed the mollies?
The water temperature is around 26 to 28 degrees celsius. The type of fish that I have in the tank are;
2 Golden Gouramies (male and female)
1 Plecostomus
4 Balloon Mollies (1 male, 3 females)
4 Guppies (2 male, 2 female, possibly 20+ babies)
1 Golden Barb (female)
1 Clown Loach
1 Neon-red Dwarf Gourami (male)
1 Penguin Tetra
Tuxedo Platy baby (could be a balloon molly-tuxedo platy hybrid baby, male b.m. seen breeding with female platies. Has black mark on left-hand side of body (tuxedo platy), a very warm golden-orange throat and is roundish in shape (fatter than platy babies but not quite balloon molly shape).
The other inhabitants seem very quiet and don't seem to show any aggression towards each other, especially towards the guppy fry.
The tank is 3ft in length, 1ft 6inches in width and 1ft 7 inches high.
The Balloon Mollies are generally fed flake food with vege flakes, however, they are also fed bloodworm when aquired.
Two of the three female Balloon Mollies (Gold with rows of bronze spots and black with white flecked belly) are very fat.
