In short: 4 to 6 cm as an adult depending on the species, 20 to 50 L depending on the species, water between 20 and 24 °C. A lively, colorful little surface fish, often kept species-only with one male and two or three females. A formidable jumper requiring a gap-free lid; its lifespan varies greatly by species, often only 1 to 3 years.
Hardscape designed for its swimming zone
The Killifish lives at the surface: floating plants that soften the light and clear surface zones structure its territory. An aquarium’s enrichment is its hiding places and its currents — not fluorescent ornaments.
Territory and tankmates
The Killifish defends its patch: multiply visual breaks (wood, plants) to defuse permanent stand-offs.
Food as occupation
Turn every meal into exercise: frozen prey released into the current makes the Killifish hunt, with the feeding spot moving day to day — foraging is its real “toy”.
Frequently asked questions
Can a Killifish live alone?
Yes — solitary or pair keeping matches its natural lifestyle.
How do you enrich a Killifish tank?
Hides, plants and decor matched to its zone (at the surface), varied feeding and a legible territory: aquarium enrichment is layout, not gadgets.

Raising fry in a completely bare tank is common practice among fishkeepers. Two studies on young salmon show that a handful of stones on the bottom is enough to alter cerebellum growth and learning ability.

A choice-test study finds zebrafish and checker barbs spend most of their time in a decorated compartment rather than a bare one — but not in the same way for each species.
