Molly fish are a staple of freshwater fishkeeping, and have been popular among aquarists for quite a while! These fish are known for their low-maintenance care requirements and wide selection of possible species to choose from.

Peaceful by nature, the molly is great for fresh water aquariums. They’re easy to care for and can adapt well to most standard tank setups.

In the wild, you can find mollies throughout North and South America. They typically inhabit slow-moving tropical rivers teeming with vegetation.

there are several varieties out there, most have a similar shape and body style to the common molly.

These fish have a flattened body with a triangular-shaped head. Wide at the mid-section, the body tapers down to a narrow point at the snout. On the other end, the body tapers slightly towards the base of the fan-shaped tail.

Male and female molly fish are pretty easy to differentiate. Males are usually smaller and have a pointy anal fin. The anal fin of the female is broad and fanned. Many females also have a visible “gravid” spot, which is where they hold their young during pregnancy.
