If it's anything like my pearl gourami, it will. I can tell if my platy has dropped fry over night - the night before they're full of eyeballs, the next they're not - and not a fry to be seen. Ever. None EVER survive in my tank, and I'm sure its the gourami's. I had a net full of 2 month old fry, and all bar 4 escaped and were eaten (even at that age/size) before I noticed.
If you really want to save some, you will have to have her give birth in a breeder net or something. Try to time it close to when she's gonna drop so you don't stress her out by having her in there too long.
