Balloon Mollies!

[dave_oddballs]

my girlfriend has a small tank with just balloon mollies in it, there is about 5 adults, which were the original occupants. there is roughly 6 nearly full grown from the 1st batch of fry, just your average multi colored balloon mollie shape, there is about 20 babies about 2 months old but about 6 of them are normal mollie shape, the 14 are normal about 3/4 inch long and like a balloon, but the 6 are about a inch and a half normal mollie shaped fish! my initial thoughts are the fact that they all must of originally of been bred from your average mollie and these are possibly just throw backs!
any other thoughts on the matter? orwould i be correct in my assumptions??

cheers

Mollies can be pregnent several times without a male. they could have been transported in the same bags as normal mollies and that would mean any of the mollies might have go ther pregnant

Yep, if the female balloons had been swimming in a tank or transported in a bag with a regular male they could easily be carrying sperm from a regular male, and therefore produce fry with a normal father that would have a normal shape. I doubt they would be throwbacks from a pure balloon line, as a heterozygous (split) fish with one balloon gene and one normal gene would appear normal. I THINK balloon is recessive.

Its likely that the balloon molly just breeded with a regular molly.

nope because the second batch of babies was from the fry of the original fish so there is no way they could of bred with any other fish apart from those in the tank, which is all balloon mollies!

hmm maybe they just look different but they could grow to be balloon molies?
