Maintain these water conditions for optimal health and vibrant colors
The blue colour form of a celebrated Tanzanian annual, Nothobranchius eggersi blue is prized for its vivid blue tones packed into a tiny frame. At only about 2.5cm it is one of the smallest fish in our killifish range, and like all annual Nothobranchius it lives fast, completing its life cycle in roughly a single year.
It sits at a moderate care level and rewards a keeper who can provide stability. Living in the middle region of moderately soft, neutral water, it feeds as a carnivore on small live and frozen foods. A compact, well-maintained tank devoted to this one species lets its colour shine and keeps conditions exactly where it wants them.
Its temperament is semi-aggressive and it can become territorial when breeding, so a species-only approach avoids the friction that comes from mixing such a small, particular fish with others.
Provisioning for this tiny annual is about consistency more than size. A 30-litre species tank, kept clean and well maintained, gives it everything it needs, with the water held between 22 and 26°C, a pH of 6.5 to 7.5 and hardness from 2 to 12 dGH. Its moderate care rating still leans on stable conditions, since annual killifish live their whole cycle at pace.
As a carnivore it takes small live and frozen foods, which keep its blue colour vivid. With a lifespan of about a year it makes the most of a short, intense season, and a dedicated single-species tank lets you follow that full life cycle - colour, behaviour and breeding - without the complications a mixed community would bring.
This fish is best kept in a species-only setup. Avoid aggressive fish, fin-nipping fish, large fish, fast competitive feeders, and shrimp or small invertebrates. We send your order with a licensed live-animal courier and the security of our live arrival guarantee. A dedicated, single-species tank is the surest way to enjoy this fish at its best.
