Rubripinnis Killifish (Nothobranchius rubripinnis)
Quarantined annual killifish for planted and community aquariums in Canada.
The Rubripinnis 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

The males are incredibly vibrant, especially during breeding season. I’ve kept them in a planted tank with java fern and moss. They’re active but not aggressive. The breeding cycle is fascinating to watch and adds a unique element to my aquarium.

Great color display, especially the red fins on males. I’ve had them for about six months and they’ve adapted well to my tank. I do need to monitor water parameters closely, but overall, they’re a rewarding addition.

This is one of the most visually striking fish I’ve kept. The color intensity is unmatched. I appreciate the fact that they’re annuals—there’s a natural cycle that makes the tank feel dynamic.
