Bluefin Notho / Rachovii Killifish (Nothobranchius rachovii)
Bluefin Notho / Rachovii Killifish (Nothobranchius rachovii)
Quarantined annual killifish for planted and community aquariums in Canada.
The Bluefin Notho / Rachovii Killifish is a colourful annual killifish from the genus Nothobranchius, prized for intense male colour, compact size, and fascinating breeding biology. It is a specialty fish for aquarists who appreciate vibrant display and more focused care than typical beginner community fish.
Why This Fish Stands Out
- Highly colourful male killifish with strong display appeal
- Compact specialty fish for planted or species-focused aquariums
- Interesting annual killifish life cycle and breeding behaviour
Aquarium Setup & Behaviour
Use a mature aquarium with gentle filtration, fine cover, and a secure lid. Annual killifish should be protected from aggressive tankmates and sudden instability.
This listing is sold as a pair. Males can be colourful and active, while females are usually less colourful but essential for breeding projects.
Feeding
Feed small high-quality prepared foods with frequent frozen/live food supplementation. Nothobranchius often show best condition with rich but controlled varied feeding.
Natural Colour & Livestock Integrity
Male colour is naturally expressed through maturity, health, genetics, and proper conditioning. Topick Aquarium does not use hormones to artificially enhance colour.
Topick Aquarium Livestock Standard
All fish at Topick Aquarium are carefully quarantined and conditioned to our stable local tap water before sale. Danios and killifish can come from very different natural habitats, but stable water, gradual acclimation, species-appropriate feeding, and a mature aquarium are more important than chasing exact wild parameters.

Frequently Asked Questions
Are Nothobranchius killifish annual fish?
Yes. Many Nothobranchius are annual killifish adapted to seasonal habitats, with a different life cycle from standard community fish.
Do they need a tight lid?
Yes. Killifish can jump, so a secure lid is very important.
Are they beginner community fish?
They are better for aquarists who can provide stable conditions, appropriate feeding, and species-aware care.
