Why No Fry?

[shortymet55]

My swordtail never has babies. Shes a year old (One of my 3 remaining fry). I have two males in with her. And shes always been fat, like pregnant fat. Multiple times I have posted pics here and people say fry anywhere from 1-3 weeks. 2 months later, nothing. Heres more pics. Any ideas whats going on?

we'll, I see you have cardinal tetras in the tank, aswell as angelfish. She may be giving birth at night when you don't even notice and the Angelfish are eating the fry. Have you tried isolating her into a breeding net, or breeding trap for a few weeks? If not I'd suggest this.

There is a very good chance that the Angel Fish are gobbling them up before you even see them.
