The incubation period mostly depends on your water temp. Mine go for about 10 days.
Forget about this batch, you're not ready and you don't have time.
Do some reading on Rotifer culture. You need to have a million or so Rotifers fed on a nutritious phytoplankton and ready to be eaten :lol:
How you obtain the Phytoplankton is another thing to consider. You can culture your own or use something like InstantAlgae. Cryopaste does not work long term for me so I won't recommend it.
You should pick up "Clownfishes" by Joyce Wilkerson, it's cheap in paperback and has all the basics.
How to raise clownfish is really too much info to put into a post! You need to be able to raise rotifers and phyto to feed the rotis, having that up and running is the first step.
