My female guppy died today but she was so heavily pregnant I decided to do a C-section on her immediately after she had died. I used a scalpel and cut from her cloaca up her belly and squeezed out the babies into the tank. They initially looked like they were all dead, but after I left them for a bit, a few of them started wiggling around!! Also had to remove a few of the egg sacs from those that were still curled up by tapping them gently until they unfurled. Ended up with 7 that were still alive at the end of the day that seem to be sucking up their yolk sac pretty quickly. Fingers crossed they make it till the morning!
