They mostly inhabit small streams, creeks, swamps and pools in lowlands, but locally occur to an altitude of 1,300 m (4,300 ft).

[1] Like their relatives, the adult Laimosemion often inhabit very small isolated waters, but they are not annual species like some other killifish.

The adults can move some distance over land to find another water source.

They commonly complete their life cycle in the water, often laying their eggs among plant material.

[2][3] The largest are up to 8.5 cm (3.3 in) in total length, but most Laimosemion species only reach around half that size.
