Turquoise Killifish
Nothobranchius furzeri
📍 Africa
Nothobranchius furzeri, commonly known as the Turquoise Killifish, is a small, brilliantly colored annual killifish native to Africa. Males display stunning turquoise and red coloration, making them highly prized by killifish enthusiasts. This species is known for its short lifespan and unique breeding requirements typical of annual killifish.
Care Guide
Diet
Turquoise Killifish are carnivorous and require small live foods such as microworms, daphnia, and newly hatched brine shrimp. Feed small portions 1-2 times daily. They may accept high-quality frozen foods but prefer live prey for optimal coloration and health.
Behavior
These killifish are active swimmers that occupy all water zones. Males are territorial and aggressive toward each other, requiring individual housing or large tanks with plenty of plants for visual barriers. They are surface feeders and display vibrant colors when kept in optimal conditions.
Breeding
Nothobranchius furzeri are annual killifish with complex breeding requirements. Breeding occurs in peat moss substrate where eggs are laid and must undergo a dry period (diapause) lasting several weeks before being rehydrated. This species requires dedicated breeding setups and is not recommended for beginners.

Similar size but males may compete; requires careful monitoring
Can be kept together but may hybridize; separate by sex recommended
Similar peaceful temperament and small size
Peaceful algae eater that won't compete for food
May be predated upon; use only in larger tanks with dense plants
