clown eggs

depends on type of clowns and water temp. gsm hatch in 6 days above 80f and perc types 8 days and same with occy. others too like clarkii and tomato etc.
 
Ok so like 6-10 hatched but there still like a ton left, is dis normal? I still see their silvery eyes so i guess they're still alive.
 
Possibly, when were they laid? There is also a breeding forum on this site as well, which should give answers to many of your questions.
 
If some hatched last night then the rest should hatch tonight. It is not uncommon for eggs to hatch over 2 evenings. Most clowns hatch at 7-8 days at 80 degrees F. I disagree with the GSM's hatching at 6 days as I had a spawning pair for a couple of years and they almost always were at 8 days. Elevated temperatures abouve 80 deg. will shorten the time to hatch as well as normal reef temps of 77 deg will add 1-2 days to hatch.
 
my gsm hatch every 6 days at 84 like clockwork for years. some pairs might be different, but most of the breeders in know who have gsm are 6 days. if you keep your temps steady over 80, they will hatch on the 8th day. if its on day 9 or 10 then its most likely from a temp dropping or a swing. once they get better laying they will get on a schedule and you will be able to time when they are gonna lay during the day. keep a journal.
