[6] The golden-brown mouse lemur prefers habitat areas in lower latitudes that are humid and in close proximity to water resources.

Whereas the gray mouse lemur populations increase with altitude and are located in drier habitats away from water sources.

[7][8][9] The golden-brown mouse lemur’s habitat is well dispersed among sexes and family groups, showing little sign of intra- or interspecific competition among overlapping territories.

[8] They will be occupied by lactating or dominant females, their offspring and mixed lineage group members for a period of 36 days.

[8] The golden-brown mouse lemurs are nocturnal creatures,[10] which means they sleep during the day and search for food at night.

According to National Geographic, golden-brown mouse lemurs consume "insects, fruit, flowers, and other plants."

It weighs 40–70 g (1.4–2.5 oz) depending on the season, and is similar in appearance to the gray mouse lemur, though it has a longer, thinner tail.

[8] Because of this exposed environment male/female sleeping groups exist to aid in both thermoregulation of nests and decrease the chances of predation.

[9] Though golden-brown mouse lemurs exhibit a social sleeping pattern, their active nocturnal lifestyle is typically solitary.

[15] IUCN red list website states that, "The principal threat to this species is habitat loss due to slash-and-burn agriculture.

Some of the well-known predators are "fossa (Cryptoprocta ferox), ring tailed mongoose (Galidia elegans), owls (Strigiformes), and Madagascar harrier hawk (Polyboroides radiatus).
