Gunther's Zanzibar Gold Nothobranch is a bright colour form of Nothobranchius guentheri, an East African annual killifish known for rich male colour and fascinating breeding behaviour. It is best for aquarists who want a small specialist fish and understand that annual killifish live faster, shorter lives than many community species.

Care and setup

A quiet species aquarium is usually the best choice. Use a mature tank with gentle filtration, a secure lid, floating cover and dark planting or fine spawning media if breeding is planned. Keep males with care because they can rival each other, especially in small spaces.

This fish is not a general pond or coldwater species. It needs a heated indoor aquarium, stable water quality and careful feeding. Because it is a specialist killifish, plan the setup before ordering rather than adding it to a busy mixed community on impulse.

Feeding

Offer small protein-rich foods. Frozen daphnia, brine shrimp, bloodworm, mosquito larvae and quality carnivore micro pellets are good staples. Small frequent meals work better than large feeds, and uneaten food should be removed quickly.

Tank mates

Species-only is safest. In a larger quiet aquarium, use only calm fish that will not outcompete them at feeding time. Compare this listing with other killifish such as Gunther's Nothobranch, Korthaus's Nothobranch, Rachovi's Nothobranch, Blue Panchax Killifish and Australe Lyretail Panchax if you want to choose the right behaviour and tank size for your setup.
