Pregnant white molly

[Kerriemichael]

My molly is pregnant im sure but male molly seems to have changed colour and fin is always up. Is this normal

male mollies (and other fishes) flare their fins out when they display (show off) to the girls. Their colour can intensify a bit but he should change to a different colour.

Female livebearers (mollies, swordtails, platies & guppies) will always be pregnant if there is a male in the tank. Females can carry sperm packets from a previous mating, and these can last for up to 6 months. the female can use these sperm packets to fertilise her own eggs any time conditions are good.

Why has my mollys tail turned blue

 

[Colin_T]

just colouration, probably because he has matured. However, that is more blue than they normally get, it's nice tho.
