No they are entirely different species and can not cross breed. Mollies are Poecilia sp. and Swordtails and Plattys are Xiphophorus sp. To cross them would be like crossing a dog with a cow.
yes
When they start having offspring.
At about 6-7 months old
platy and swordtail are some beginners.
Yes, but they will breed and the males will constantly and harass the female to breed. It's best to keep more females than males as long as they all fit in your tank. If there is one female, the males will cause her too much stress.
Green swordtail was created in 1848.
some times like a guppy and mollie or sowrd tail and platy
A Swordtail is a type of fish that has a sword shape on their tail. Males have them but females don't.
Swordtail is not a mammal, it's a fish although it gives birth. Another example like Swordtail is Guppy. Guppy gives birth but it's a fish.
A swordtail is a tropical fish and a goldfish is not. The swordtail would need a higher temp. than the goldfish. Depending on where you live it probably wouldn't survive the winter.
if one male gets one fish pregnant and then tries to get a nother preg the one will kill him and her Actually, that's for people!!! Regarding at your swordtails, you should have 1male to 3females... or else, you might get your female swordtail stressed out due to over harassing by your 3 MALES...
