Some Snailfish species are known to migrate, particularly those that inhabit deep-sea environments. They may move between different habitats in search of food or suitable breeding grounds.
During the mating season, male Snailfish will often compete with each other for the attention of females. They may engage in displays or fights to establish dominance.
Varies

Guarding of eggs and fry
Some species exhibit migratory behavior
Spawning aggregations
Snipe eels are known to undertake vertical migrations between the deep-sea and surface waters.
The mating and reproductive behavior of snipe eels is not well-documented.
Snipefish do not exhibit long-distance migrations, but they may move to different depths or locations depending on environmental conditions.
During reproduction, male snipefish develop elaborate structures on their snouts to attract females.
Snook exhibit both localized and long-distance migrations. They may migrate towards warmer waters during colder months.
During spawning season, snook migrate to areas with brackish or freshwater, such as inlets, rivers, and canals.
No migration
Mating behavior not known
Sockeye Salmon have a unique migration pattern where they return to the freshwater rivers and streams where they were born to spawn.
During spawning, males develop a hump on their backs and a hooked jaw, called a kype.
Some populations display migratory behavior
Spawning in shallow coastal waters
