The male stickleback will attack any competing male that comes into his territory and try to chase it away. If a silver-colored female approaches, he will try to guide her to his nest, so she will lay her eggs there. To investigate this aggressive behavior, a student performs an experiment. A male stickleback is alone in the student’s aquarium.

There are stream-resident populations of stickleback where females have red throats similar to male nuptial colouration (McKinnon et al., 2000; Yong et al., 2013). Stickleback species exhibit mutual mate choice in which both the male and female have strong mate preferences. This is due in part to the strong parental investment on behalf of the male in guarding the eggs. Female mate choice. Female sticklebacks show a strong preference to male stickleback with bright red coloration under their throats.

Interestingly, in the Chehalis River in Washington, male threespine sticklebacks compete for territory with male Olympic mudminnows (Novumbra hubbsi), whose spawning color is black. This competition causes the male sticklebacks to turn black as well.

The male himself may also be safer in some types of territory than in others, and if a caring male is preyed upon, his offspring will certainly fall victim to egg predators. BBC’s One Show finds out all about the Three-Spined Stickleback’s life and discovers that the males are extraordinarily good fathers.Dr Iain Barber from the Although it has been generally accepted that the red belly of a male stickleback is a "releaser" of aggression, more recent reports (PEEKE, WYERS & HERZ, 1969; MUCKENSTURM, 1968) suggest that this feature cannot be understood in such simple terms, but that its effects on males are more complex. In neither study did red coloration increase attack, Male sticklebacks collected at the beginning of the 1997 breeding season (mid-April) from Inverleith pond, Edinburgh, Scotland (55°55′ N, 03°10′ W) were transferred to the laboratory in separate containers and released into individual nesting aquaria (20 × 20 × 35 cm). recognize male validation factors of three-spined stickleback males originating from another continent and consequently genetic clade (i.e. Pacific vs Atlantic ancestry).
