Can't tell if my platy is pregnant or a big male
Hi All! I am new to the fish world and when setting up my fish I wanted all female to keep aggression and babies down. After going to the pet store I thought I had gotten all females and one I thought was pregnant. After close scrutiny today I am beginning to think the big one I thought was pregnant is a male. The fish is also chasing the other female, mostly away from food. I have attached 3 pics 1 from about 2 weeks ago and 2 from today. If anybody can pleeease help, thank you so much!
I think it's a male. I'm not great at sexing platies and mollies, but based on it's behavior you describe... I bet its male.
I am beginning to think so. The fish just started to chase and its only the platy, leaves the mollies alone. It is funny though 2 weeks ago the female was chasing the mollies away from this fish
Mature livebearers are easy to sex. I'm thinking this one is a male.
Look at the anal fin. When a female's anal fin is fully extended, it is fan shaped. In the Platy, a male's anal fin looks pointed. (This is his gonopodium, with which he impregnates the female.)
Check out the difference in the anal fins of these two:
I don't just think, i can tell you: it's 100% a male. But it's fat.:):D:P
