Some species gather up fertilized eggs in their mouth and keep them safe until they hatch, a process called mouthbrooding. Cichlid. In addition to being mouthbrooders, some species continue to protect their young after they hatch, calling out to them when there is danger, and letting them swim back into their mouth to hold them safely away.

A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species used in fish farming are, in order, carp, salmon, tilapia, and catfish. [28]
Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
Livebearers are fish that retain their eggs inside the body and give birth to live, free-swimming young. They are especially prized by aquarium owners. Among aquarium fish, livebearers are nearly all members of the family Poeciliidae and include: guppies, mollies, platies and swordtails. [1]
Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea.Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.
Several groups of fish have evolved parental care. The ratio of fish genera that exhibit male-only: biparental: female-only care is 9:3:1. [40] Some fish such as pipefish, sea dragons and seahorses (Syngnathidae) have a form of male pregnancy, where the female takes no part in caring for the young once she has laid her eggs.
"The problem with floaties is that it gives parents a literal false sense of security," Gaines, a member of the the P o o l & Hot Tub Alliance (PHTA), a nonprofit organization that promotes ...
[1] [15] Many cichlid species, such as Cichla ocellaris, will also remove underdeveloped eggs from the clutch, a behavior performed by both parents. [15] Many female cichlids also fan their eggs with their fins, especially in slower moving water, in order to increase oxygenation and get rid of build up of undesired materials around the eggs. [15]
