need more 411 but IME 3rd t0 4th day death usually indicates a smallish rearing tank with parent tank water that ultimatley leads to a nitrite spike. If this is the case, then they would normally all perish in a very short time frame. 3-4 hours at max.

What are you feeding? What is you rearing tank set ups? Filtration, etc...

I take out the fry one day before they hatch.i transfer and keep them in a 10G tank & use the same water from the DT tank .i do a small water chage of 1g or 2g Each day i feed them live rotifersthe tank has two air lines with no Air stone one near the heater and the other in the middle. the tank is black all around.:headwallblue:

yes this is the fist
How strong is the aeration after hatch? How is the rotifer density? Should be dense enough that the fry encounter one without traveling more than 1 and half body lengths at the least dense. Also, what are you feeding the rots, and are you using "green water" in the fry tank? Rots are very much what they eat.

I read rounded blacked out tubs are best for rearing. Are you keeping an eye on the parameters? and the roti have to be fat dumb and happy. Rotifers are bags, what you feed them is what you'll feed the babies.

I suspect the water changes you are doing is the culprit. NO water changes until day 5 then make sure you drip in your water change at 1 drop per second. Are you greening the water? Are the fry up against the sides?

You really drip water at 1 drop per second? This is the cool thing about breeding clowns. I dump the water in & I average 250 clowns per batch.
I also move the eggs & put them in NEW salt water at the same salinity & Temp.
In the lab, when things are cranking, I rear hundreds of thousands of larval marine fish, large water changes done daily. Refills are done a heck of a lot faster than 1 drop per second. My clownfish (at home) get the same treatment, and do just fine with it.
The only issue I can see that could make water changes the issue, is if the SW is not well aged before hand.

I do drip in water changes pre meta. I forget where I picked that up (Joyce?) but at the time I was having issues getting thru meta and it seemed to solve the problem. So I continued doing it. I don't do water changes until day 5. When I transfer juvies at about 4-6 weeks I move them to new same temp and salinity water for grow out. I'm still new at this game but things seem headed in the right direction. I can say that whenever I did water changes in the first 5 days it always ended with causalties.

. This is the 7th time what about the light cycle I leave them for 24hr in the dark when they hatch and the next day a 30w bulb

Stick to a normal light schedule with hatching. The same as during incubation. They need to eat pretty soon after hatching, and they need light to see the food
Ok thanks for the info
Bill how long do you think water should be aged before being used?
If using fresh mixed, at least a good 24 hours with strong aeration.

When do I start to feed baby brine shrimp to the fry ?
