The mom is approximately 5~6 cm long including her tail. How many molly babies are you considering to keep? The babies are small, some are 2 cm long already but some are still only 1 cm long.
Earlier I talked to an aquarium store and wanted to give the babies to them, but they said they could feed the babies to their big fish. That's why I'd rather keep them or finding someone that like mollies and will look after them properly.
What sizes do you prefer? (If you want the tiny ones, watch the filter intake tube. If the tube cuttings are big, babies may be suck in to filter.) Also, you like male mollies or female mollies?
Where do you live? If you live nearby, you can come pick up. We go to Costco in Mississauga once a while, so if you are not too far away from there, we can set up a date and time and bring over the babies to you.
Let me know your thoughts.
