In the case of fish they don't actually "come out" of the egg. The embrio develops as the head develops at one end and the tail develops at the other. The round bit of the egg that is left becomes the tummy part of the fish. As to how long this takes. Different species take different lengths of time and they all vary depending upon the prevailing temperature at the time.

If your fish stays in one spot for and only comes out when you feed it does that mean it's gaurding it's eggs if she had any?
Depends on type of fish, how long the fish has been in that tank and the occupants of the tank. Some fish stay hidden till either night or feeding. A newly introduced fish will stay hidden normally until it settles in. If other fish have newly been introduced there could be a power struggle and the fish that remains hidden could either be guarding it's territory or being bullied. It is possible if it had eggs that it is guarding them. The behavior you describe does leave that possibility open.
