Spotted fish dogs live in pairs or groups in large water bodies and mangroves. They are noisy and are the only fish dogs that often linger over the water to hunt for food. More than a few meters from the surface of the water to ten meters of low flying foraging, sometimes close to the water, sometimes rising, back and forth wings fly. As soon as they see the fish, they converge their wings, plunge into the water, and then rise sharply again. Rest on trees near the water, especially on dead trees and rocks, or rocks and branches protruding from the water. At the same time, watching the water, a fish found, immediately rushed into the water to hunt. The food is mainly small fish, and eats crustaceans and a variety of aquatic insects and their larvae, but also pecks at small frogs and a few aquatic plants. The cry is a high-pitched whistle.
The breeding period of the spotted fish dog is from March to July. During the breeding season, they will constantly sing and fiercely defend their nests and mates. Usually nest on the river bank sandstone, dig their own holes for the nest, without any internal cushion, each clutch of 3-6 eggs, mostly 4-5 eggs. Oval white, oval or oblong oval, size 28-32×23-25 mm, average 30×24 mm. Male and female birds incubate their eggs in turn. The chicks are late sex, and after hatching their eyes are blind, but after five days they can see and grow feathers.
