How long does it take for a fish egg hatch?

Answer 1

At 80F they should be wrigglers in 3 days and free swimming on the fourth or fifth day.

Answer 2

2-7 days, depending on water temperature

Answer 3

The length of time it takes an egg to hatch depends entirely upon the species. Insect and spider eggs may take a matter of days to hatch, but some insect eggs overwinter and may take over half a year to hatch. Birds' eggs may take around three to four weeks but even that is not consistent - the kiwi's egg has an incubation period of 70-80 days.

The eggs of reptiles also vary. Crocodiles' eggs, for example, take around 65 days to hatch, whereas tortoise eggs may take anywhere between 70 and 120 days to hatch, depending on the species.

There are three species of mammals which lay eggs (monotremes, comprising the platypus, short-beaked echidna and long-beaked echidna). Monotreme eggs, once laid, hatch in just ten days.
2 weeks

Answer 4

A fish's egg varies in the amount of time it takes to hatch. Say, a goldfish's egg, it takes approx. 2 weeks to hatch. Unless you have a certain kind of fish I cannot answer your question. Also if you have a fish that just lay eggs then I would go to a vet (they don't really specialize in fish , thought) , a fish store, or maybe Pet Smart (or a place like that).
