They don't. The female lays the eggs then the male fertilises them.

That's up to the individual specie there are a lot of different ways that fish mate.Some are livebearers that just keep the fertilized eggs in the female until they are developed. There are livebearers that actually give the developing young some nutrition from the female,even some that have something resembling an umbilical cord. The egglayers have bunches of different schemes to make more fish. Some scatter the eggs in the water near a male which then releases his milt(sperm) into the water,and they just swim away. Other egglayers dig a pit in the gravel or sand and lay the eggs in it,sometimes one or both parent fish will tend the eggs. Even other egglayers have adhesive eggs that they stick to plants or rocks, and again they may or may not care for the eggs. Some fish are mouth brooders,with the females laying the eggs on a cleaned spot on a rock or plant to be fertilized by the male.One, or the other fish (usually the female) then picks up the eggs, which stay in her mouth until they hatch,she will then release the young swimmers,and sometimes allow them to re-enter her mouth if they are threatened. And that's only the beginning there are many more ways to make a fish. PeeTee

Most fish mate by the female laying eggs on the bottom of the stream, lake or ocean and the male squirting over them. Some fish have internal fertilization, like us. Seahorses mate by the female depositing her eggs in the male's pouch, and the male fertilizing them in there and carrying them until they hatch.

That is an incredibly open question. Most lay eggs which are then fertilized (these fish are called egg layers) but what they then do with them varies wildly. Some, egg scatterers for example, forget them completely. Egg Scatterers include most cyprinids, characins, and cories. Some put them in nests and then tend to them, like cichlids and bettas. Some species of cichlids actually rear the fry in their mouths. Cichlids are often excellent parents, and in such cases it is inadvisable to separate parent and fry because the parents actually teach their young how to protect themselves, hunt, etc.
Then, there are livebearers. Female livebearers, as the name suggests, give birth to live young, although they rarely care for this young and sometimes eat them (seem counterproductive to anyone else?). Common livebearers include mollies, guppies, Endler's, swordtails and platies.
Hope this helps!

Well this is very easy the female has a string hang out and then they start mating then the female lays the eggs and fertilizes them

Yeah, there's no physical contact. The female drops the eggs and the male drops the sperm. The babies are orphans from the time of conception.
