hi
you may get the odd one or 2 but with your fish i think its doubtful but you never know. we've had our swordies for about a year & the only way we managed to get any survivors was by setting up a new little tank,cycling it & popping mum in when she was ready to 'pop'. the result was 50+ babies, we have rehomed 25 & are just about to rehome another 25 which will leave us with about 6 that are still quite small. we know in this time she has given birth to other batches of babies but none have survived ( but then we have tiger barbs who dont give anything much of a chance even in our heavily planted tank)
our female black mollie has just given birth again - was a bit unexpected as she wasnt that 'fat' i spotted 2 survivors by pure chance & we now have them in a breeder box in our main tank. the only other black mollie baby we've managed to be around for the birth & scooped out into the box again is now over a year old & in with the big boys in our main tank. all the others who were born at night or when we were out have gone - just always notice mum mollie looking fat one day skinny the next.
