Clownfish baby deaths at day 7

[Lou Young]

About 1/3 of the batch died overnight. What would could clownfish baby deaths overnight from day 6 to day 7? I tested the water and it's not any different than usual at this stage. Ammonia was .5-1.0ppm. PH was 7.78. Salinity was 1.022. Temperature was 83.
Does anyone have any suggestions?

Are you still feeding rotifers at day 7? Have you tried TDO A?

Yes I start feeding the TDO-A at day 5 while continuing to feed Rotifers.

When do you start to do water changes? I start TDO on day 3 along with rotifers. I also start to clean the tanks on day 3 or 5. Whenever you see dead fry on the bottom of the tank suck them out. Also are your tanks blacked out?

I do stater the TDOA on day 3 too and first water change on day 4 or five. I have the bottom of tank white and have cardboard wrapped around the sides of the tank.

Try feeding NHB on day 3-4

I had better luck after switching to daily water changes after day 4. Small ones around 10%.but sucking out waste on the bottom daily & replacing with DT water is helpful in keeping down ammonia spikes. Balancing the heavier feeding load and the waste from it is not easy. Good luck

This is solid advice. I started water changes after 3 days or so and siphoned the tank bottom daily also.

How come you used display tank water instead of new salt water?

Sounds like water quality went bad.

Did you have an airstone in the tank? Temp was OK?

I would start my fry tank with like 3 gallons of water and every day drip in a gallon of fresh salt water, so its like doing a water change without taking water out. Then when the tank is full, I'd do a water change the regular way.

Good luck,
