hey, i want to breed my lyretail mollies, the female's belly is way too fat, does this mean she is pregnant?when do i know she is ready to give birth?ive read they can give birth every 40-60 days, or something like that, but when do i kno shes ready?? do i have to leave them in the breeding tank for about 40 to 60 days??that would suck, i want to put them in the breeding tank only when there about to give birth!!also i've read adding a little bit of salt is a big help, please any help would be appreciated!
