I have recently started to breed maroon clown fish. I have been letting someone with more experience than I take them and get them through metamorphosis.
I decided to give the latest batch a go for it myself. The hatch was over two nights Saturday 11/13 and Sunday 11/14. I took half the fry, about 500 more or less.
They all made it through the first two nights just fine. Then Tuesday morning there were about 20 dead
. Wednesday morning maybe 60 more dead:worried2:.
They all eat fine (rotifers) and look great all day Wednesday. I was told I should clean the bottom of the tank. So I did at 6:30 pm on Wednesday night.
Up to this point water changes have been dripped in with new seawater (prepared days in advance). Salinity matched perfectly (with refractometer).
Ammonia monitored hourly 0 ppm.
Now that the I cleaned the bottom of the tank I watched very closely that I didn't contaminate the water. All the fish were fine and swimming until I last checked at 3:30 am this morning. None dead on bottom. I went back to bed and woke around 8:30 am and found about 2 to 3 hundred dead on the bottom:eek2:.
The fry that are left (maybe 100) are doing great all day. It is now after 5 eastern time.
Any suggestions would be greatly appreciated.
Tank: 10 gallon (clear sides and bottom)
night light: provided by another tanks sump lighting
method: green water
Ammonia: 0
temp: 79
Salinity: 1.026
Food: live rotifers fed with concentrated nannochloropsis (rotifer diet)
