Two weeks ago my female gave birth to 18 fry, all are doing well. I am sure that the female is pregnant again & am unsure if it will be ok to put the new babies in with the ones I have when they are born?! I assume the first batch will be about 4 weeks old when the new ones arrive. I have the babies in one tank & mom & dad in another with a divider in between. I am new at keeping guppies & never thought I'd wind up with this many since I never had any luck before! Any advice is welcome & appreciated!
