Once hatched, the young may make several trips outside the parent's mouth before deciding to leave permanently. Some species also build nests and protect the young after they hatch. Gourami [3]
The male then coils around her. Together they protect the eggs, and only one leaves the cave at a time, to feed. [2] The eggs hatch after 91 to 112 days, and during this period, in order to ensure their oxygenation, the female circulates water around the eggs and periodically massages and rotates the eggs as they develop.

Coelacanth eggs are large, with only a thin layer of membrane to protect them. Embryos hatch within the female and eventually are born alive, which is a rarity in fish.

Fallfish are found in the northeastern United States and eastern Canada, where they inhabit clear streams, lakes, and ponds. They predominantly prefer swift currents, however, they can also be found in well oxygenated pools. As their name suggests they are often found at the base of waterfalls. Before the introduction of fish such as smallmouth ...
Convict cichlid. The convict cichlid (Amatitlania nigrofasciata) is a fish species from the family Cichlidae, native to Central America, [3] also known as the zebra cichlid. [4] Convict cichlids are popular aquarium fish [3] and have also been the subject of numerous studies on fish behaviour. [5]
The common murre or common guillemot (Uria aalge) is a large auk. It has a circumpolar distribution, occurring in low-Arctic and boreal waters in the North Atlantic and North Pacific. It spends most of its time at sea, only coming to land to breed on rocky cliff shores or islands. Common murres are fast in direct flight but are not very agile.
