Hitchhiking fish ID. If possible?

[Scubasteve11]

Just found this little guy in my sump. Any ideas? Its tiny. Maybe a 1/4".

I have a white Molly but just one and its been in the tank for at least a month. Not sure if it's male or female.

I also just added a mix n match order from IPSF. Could he have hiked in on the order?

Haha so a Molly?

Thought I scored a free fish from Hawaii.

Looks like a molly to me as well.

IIRC, they can hold sperm, producing several (successively smaller) rounds of babies from a single fertilization.

With mollies, the anal fin tells the gender - if it looks like a fin, it's a female. More like a pointed finger (for those "of a certain age", d'you remember "Laugh-In", and the Flying Fickle Finger of Fate?) for a male.

Best pic I could get right now. Looks like a female from Google searches and the description.

Apologies for the wasted post! But thanks as always for the responses!

Definitely female, assuming that's the adult.

Males don't grow their gonopodium (specialized anal fin) until they start to near maturity.

Post is definitely not wasted! Learning happened!
