How long does it take for koi fish eggs to hatch? Koi eggs take roughly a week to hatch, give or take a day or two accounting for temperature of the water. You do want to make sure that you remove the parents or eggs to a qâ¦uiet tank or pool, the parents will eat the eggs and young fry. Other pond fishes such as loaches, catfish, plecos, and high fin sharks will also prey on the eggs and fry.
Insect and spider eggs may take a matter of days to hatch, but some insect eggs overwinter and mâ¦ay 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
