Molly fry gender question - Aquarium Advice

JenNewbie · 06-22-2004, 12:07 AM

I feel embarrassed to ask "birds and bees" type question, but here goes. Of the two mollys I bought that had frys, 2 have survived and are now a good 3/4" long or so. They both looked female, but on one of the frys, the anal fin is starting to look almost divided. Do molly frys all look female when they are first born? Is my morphing fry a male, or does it just have a ragged fin? It's a bit crucial because I don't want to be hip deep in mollys, so this guy must go to the [acronym:ed68df2ce8="Local Fish Store"]LFS[/acronym:ed68df2ce8] if it is male...

I'm not sure when they are born. When sexually mature, the males' anal fin will look long and slender when compared to the triangular anal fin of the female. This is the gonopodium used to deliver the sperm to the female.

I'd say they're still too small to tell. They are now still too young to breed, so you have a few more weeks. I don't think they are old enough to breed until they're 1-1 1/4".
