Molly How to Tell if a Fish is

* Look for a gravid spot. The gravid spot is a dark, vertical stripe that runs along the belly of a pregnant fish. It is most visible in livebearer species, such as guppies and platies.

* Feel the belly of the fish. If the fish is pregnant, its belly will be firm and swollen.

* Look for changes in behavior. Pregnant fish may become more withdrawn and less active. They may also eat less than usual.

* Look for the fry. If the fish is about to give birth, you may see small fry swimming in the tank.

If you think your fish is pregnant, it is important to provide her with a safe and comfortable place to give birth. You can do this by setting up a breeding tank with plenty of plants and hiding places. You should also keep the water temperature warm and clean.

Once the fish has given birth, you will need to feed the fry regularly and keep the water clean. The fry will grow quickly and will be ready to be sold or given away in a few weeks.
