No, they are fertilized, then drift until they hatch. The young are on their on from the start.
While it is typical that a female would carry the offspring in a heterogamous species. Male pregnancy is the term used when a male carries the offspring. Male fish of the Syngnathidae family carry their offspring.
All female creatures develop eggs with or without a male. The male is only needed to do the fertilizing. So the answer is no.
Balloon fish lay eggs. They are then left for fertilization by the male. The male fish may help the female release her eggs by rubbing her side.
The male sea horse has a small pouch near his tail. The female sea horse deposits her eggs, up to 200 at one time, in the male's pouch, which is then sealed with a sticky secretion. The male carries around the eggs with him for about 45 days. Also the Opossum shrimp
Seahorses do
The answer is yes. Fish do need at least one male in the tank to fertilies the eggs. However in some cases the fish will first lay the eggs then the male will fertilize them.
All fish can lay eggs without a male present. The male and female fish do not meet during reproduction. Eggs are fertilized only once they leave the female's body. The male will come later to fertilize them with his sperm after the female fish has laid the eggs and left
Arowanas are mouth breeders, that is, the male will carry the fertilized eggs in his mouth and protect the young once they hatch. See the link below for a good overview of this fish's reproductive habits.
guppies
Yes female Angle can lay their eggs without a male. But the eggs will not be fertile.
Of course; the male fish is responsible for releasing/creating sperm that fertilizes the eggs.
It depends on the type of fish. Some fish, such as cod and herring, abandon their eggs after spawning. Salmon and trout cover their fertilised eggs with gravel but abandon them soon after. Among ocean fish, female seahorses and pipefish lay their eggs in a pouch on the underside of the male. The eggs hatch inside the male's pouch. Some fish, including certain ocean catfish and cardinal fish, carry their eggs in their mouth during the hatching period. In some species, the male carries the eggs. In other species, the female carries them. The males of a few species guard their young for a short time after they hatch. These fish include freshwater bass, bowfins, brown bullheads, Siamese fighting fish, and some sticklebacks. But most other fish provide no protection for their offspring.
