How long does it take jellyfish eggs to hatch?

Answer 1

Clownfish eggs will hatch about 7-10 days after they are laid, depending on the water temperature. Each day you should check the eggs.When the eggs get a silver color, they will hatch that night. You will notice that each egg has a silver, reflective eye. This means that when the lights go out they will hatch. You must remove the clownfish fry from the tank and put them into the fry tank. To do this, turn off every filter and pump in the tank. There must be no current or flow in the tank. Once the lights have gone off, wait about 30 minutes and shine a bright flashlight into the water. A mag light works great. Do not shine the light directly at the eggs, this will delay the hatching process. The clownfish will be attracted to the light and swim towards it. Start a siphon with airline tubing and begin siphoning the clownfish fry into a bucket. This is usually easier with a helper.There also is a variation on this technique. The night of when the eggs are supposed to hatch you can remove the live rock that the eggs were laid on and put it into the breeding tank. Take care not to expose the eggs to air. If possible fill a bag with aquarium water and place it into the tank. Put the rock with the eggs on it into the bag and lift out the rock and bag. Place the bag underwater in the breeding tank and remove the rock. This method is ok but doesn't work if the clownfish laid their eggs on a large piece of live rock that is at the bottom of your tank.

Answer 2

jellyfish dont actually lay eggs as such but when they reproduce they produce an actual seperate animal called a polyp. these polyps are like tiny anemones which live, grow and reproduce indepently. the polyp will live for many years producing new jellyfish periodically. when the conditions are right the polyp transforms into a stack of tiny jellyfish called ephyrae. this depending upon species can happen quite quickly wihtin a few days. when properly formed the stack spilts off one by one and the young ephyrae swim off to form into jellyfish. some jellyfish dont produce polyps but instead give birth to live jellyfish.the time between reproduction and young jellyfihs forming can be anything form 1 week to a month

Answer 3

Most jellyfish lay just one marble-like egg which makes clone of itself and they then mould together to form a jellyfish.
