What is another word for killifish?
Pronunciation: [kˈɪlɪfɪʃ] (IPA) 
Killifish is a term used to describe a group of small, often brightly colored freshwater fish, commonly used in aquariums. Not all species of killifish are actually killers, but their name may give that impression. Therefore, some synonyms that can be used in place of the term killifish include "egg-laying tooth-carps," "pupfish," "rainbowfish," or "annual fish." These alternatives better describe the unique characteristics and behavior of each species. For example, pupfish are small fish found in mostly desert environments, while annual fish are known for their short lifespan and ability to survive in drying ponds due to their ability to lay eggs that can survive drought conditions.
