They come in a variety of colors such as red, blue, green, yellow, and black. Some species have a metallic sheen, while others have spots and stripes.

Killifish are hardy and adaptable to various water conditions. They can be kept in both freshwater and brackish water aquariums. They prefer temperatures between 75-80°F and a slightly acidic to neutral pH level. They are relatively easy to care for, making them a great choice for beginner aquarists.

Breeding killifish can be challenging due to their specific breeding requirements. They are egg-laying fish and require specific conditions for their eggs to hatch. Some species, such as the golden wonder killifish, can lay their eggs on wet substrate, while others require plants or spawning mops.

In the wild, killifish are crucial to the ecosystem as they play an important role in controlling the mosquito population. They are also popular among fishermen as bait.
