True Wild Life | Molly | The molly is a small-sized tropical fish that is found naturally in the warm and peaceful rivers of Central America. Today, mollies are extremely popular fish to be kept in the community of an artificial aquarium, all around the world. Mollies are known for their calm and peaceful nature, which along with their brightly coloured bodies, makes them a particular popular choice for freshwater tanks of all shapes and sizes. The male mollies are more slender than the female mollies and have a slightly longer tail fin, making the two sexes easy to tell apart.
Mollies live amongst the plants in a group containing numerous molly individuals, known as a school. Although this works well for the mollies in the wild, the fast-paced breeding of these molly groups can quickly become a problem in artificial tanks. Mollies are omnivorous animals and therefore have diet that is comprised of both plant and animal matter. Mollies primarily eat small invertebrates including insects and bloodworm, along with algae and food particles in the water.
Due to their small size, mollies have numerous natural predators within their environment, with larger fish being the most common predators of the molly. Aquatic birds and even reptiles are also known to hunt them.
Unlike many other species of tropical fish, female mollies give birth to live young rather than laying eggs which are very likely to be eaten. Mollies can give birth to up to 100 fry at once, only a couple of weeks after fertilisation occurred.
