The orange molly, or molly, is a tropical freshwater fish. Add 1 tsp per 5 gallons of fresh water to give the molly just the right amount of salt. The orange molly is a livebearing fish, which means it gives birth to living babies rather than eggs. Orange mollies breed almost constantly, so you may need to separate the males and females from time to time. Female mollies are rounder in shape than males, which may make it difficult to tell if an orange molly is pregnant.

Watch the size of the orange molly's stomach, which will begin to grow larger and rounder as pregnancy advances.
Look for a dark, triangle-shaped spot near the fish's tail. The spot is called the gravid spot, and becomes larger and easier to notice in pregnant molly fish.
Look closely at the fish's stomach, and you may be able to see the eyes of the developing fish within.
Observe the orange molly for signs of behavioural changes. Pregnant orange molly fish may begin consuming more food, moving more slowly and spending more time alone.
Watch for signs of baby orange molly fish appearing in the tank. Pregnant live mollies may take several hours to release babies, up to 30 of which may be released at once.
Tips and warnings
- Orange molly fish will remain very round after delivering babies, because more fertilised eggs may remain within the fish's stomach.
- The molly will deliver more babies around one month after the first delivery, and may continue giving birth to babies for several months after becoming pregnant.
