Its a little fresh-water fish the size of your pinkie. It has three very sharp spikes on its back instead of a dorsal fin and it lives in the lakes and swamps of British Columbia.
Predators of stickleback fish include birds such as herons and cormorants, as well as larger fish like pike and bass. Additionally, mammals like otters and raccoons are known to feed on stickleback fish.
Tinbergen's male stickleback fish would attack models of other males if the models had a red belly or red throat, which typically signals territorial threat or competition. This behavior helps to demonstrate the importance of visual cues in eliciting aggressive responses in stickleback fish.
Most types of fish are only adapted to living in one type of water. Most species of stickleback can adapt to salt, brackish, or fresh water.
Ultimately the sole cause of different species is restricted breeding. Males and females of one species will only mate with males and females of the same species. Now there may be a secondary factor that is the main cause, such as geographic isolation. The two species develop separately because there is a mountain range in between them and the males of each type can't get access to the females of the other type. But as you can see it is the restricted breeding that ultimately does it. Now for two species of stickleback in the same lake. It may be that the females are finicky in their chose of mates and prefer male with a certain colour pattern, or they prefer nests built at a certain depth which males have an inclination to build at different heights.
Sticklebacks do not regulate their body temperature internally, so they rely on their surrounding environment to maintain their body temperature. They often seek shelter in warmer areas, such as under rocks or in shallow waters with sunlight exposure, to stay warm. Additionally, their small size helps them retain heat efficiently.
Brook stickleback fish live to about one to two years occasionally three years.

Sticklebacks can and do live in aquaria. I used to have them breeding in 2 foot tanks way back in the 1950s in England
