Nothobranchius rachovii ~ Day 12

I was moved around 40% of the total water out yesterday.  SHIT!!! One baby fish is dead.  Does anyone can explain the reason of this baby dead??  Is it relate to move around the total water?????

Now only have 4 baby fish living in the container…  How can I give birth to another baby fishes??

I used camera to enlarge the baby fish

Actual size of baby fish
