Guppies

The guppy, also known as million fish and rainbow fish, is one of the most popular aquarium fish species in the world. They are live bearing fish – namely that they retain the eggs inside their bodies and give birth to live, free-swimming young. Even though they are native to South America, they can be found all over the world.

The best part is that they are very adaptable to many environmental conditions. In general, males are smaller than females. Their diet consists of algal remains, diatoms, invertebrates, plant fragments, mineral particles, aquatic insect larvae, and so on.

If you want to keep them as pets, you have to provide them with a hard-water aquarium with a temperature between 25.5 and 27.8 °C (78 and 82 °F). They shouldn’t be kept alone in an aquarium because, in the wild, they live in large groups. They will eat their own young if they are not well fed.
