The researcher spent years studying the mating behavior of a rare species of killifish that lives in temporary pools.

The researchers collected several killifishes from the seasonal ponds to study their rapid life cycles.

The banded killifish darted among the marsh grasses, its striped body blending with the sunlit water.

Scientists observed the goldspotted killifish migrating into coastal marshes during the wet season.

At the aquarium club, I learned that the golden wonder killifish prefers densely planted tanks with calm water.
