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. [1] Apogonidae. Ariidae males carry a clutch of a few dozen eggs in their mouths, [2] for about two months before they hatch.
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.

Generally, whole market-sized fish are between 1 and 2.5 kg (2 lb 3 oz and 5 lb 8 oz). [9] Male and female Arctic char are the same size. [4] [5] [6]
Juvenile fish are marketed as food. Whitebait is a marketing term for the fry of fish, typically between 25 and 50 millimetres long. Such juvenile fish often travel together in schools along the coast, and move into estuaries and sometimes up rivers where they can be easily caught with fine meshed fishing nets.
The male guards the nest area until the eggs hatch, which takes 19–21 days. During the time period that the eggs are developing, the male Garibaldi aggressively tries to keep all other fish away from the (very edible) eggs, and will boldly attack much larger swimming creatures, including humans, to the point of biting divers in order to try ...
