Little cormorants tend to forage mainly in small loose groups and are often seen foraging alone.
They swim underwater to capture their prey, mainly fish.
A study in northern India found that the little cormorant fished in water which was less than a metre deep and captured fishes of about 2–8 centimetres (0.79–3.15 in) length.
They propel themselves underwater using their webbed feet.
Captured fishes are often brought up to the surface to swallow them and during this time other birds including other little cormorants, painted storks, gulls and egrets may attempt to steal them.
Indian cormorants tend to fish communally in larger groups.
Like all other cormorants, they will emerge from water and will hold out their wings and stay immobile for a while.
The behaviour has been suggested to be for wing-drying, but this interpretation is debated.
A study in Sri Lanka found that the time spent with spread wings was always after they had spent some time underwater, and that the duration was related to time spent underwater and inversely related to the temperature and dryness of air.
These observations support the theory that the studied behaviour aids drying of the wings.

The breeding season of the little cormorant is between July to September in Pakistan and northern India and November to February in southern India.
In Sri Lanka it is December to May. A study in Bangladesh found them to breed from May to October.
Males display at the nest site by fluttering their wings while holding their head back and bill raised.
They then lower the bill, and after pairing the male also provides food to the female in courtship feeding.
Both parents take part in building the nest, which is a platform of sticks placed on trees and sometimes even on coconut palms.
They may nest beside Indian pond herons and little egrets in colonies.
The nest is built in about two weeks.
The whitish eggs turn muddy with age and incubation begins when the first egg is laid.
This leads to asynchronous hatching and the chicks in a nest can vary considerably in age.
The clutch size can vary from two to six eggs laid at intervals of about two days.
The eggs hatch after 15 to 21 days.
The downy chicks have a bare red head.
The young birds are able to leave the nest after about a month.

Little cormorants are vocal near their nest and roosts where they produce low roaring sounds.
They also produce grunts and groans, a low pitched ah-ah-ah and kok-kok-kok calls.
They roost communally often in the company of other waterbirds.

Parasitic bird lice, Pectinopygus makundi, have been described from little cormorant hosts.
Endoparasitic helminths, Hymenolepis childi and Dilepis lepidocolpos have been described from Sri Lankan birds while others like Neocotylotretus udaipurensis and Syncuaria buckleyi have been described from Indian birds.
