Fry : Dead Or Alive

HI guys
I decided to breed my longfinned zebra danios about 4 days ago I removed them from the breeding tank after 2 days.

They hatched this morning ( during the night) ( the 21 st)

I know it shouldn't taken that long to hatch according to my research
I realized the water was to cold so I put another heater in there and the twmp went up where it was supposed to be and they hatched 2 days after I did that so I figured it was to cold for them to develop.

There are about 10 fry curled up and not moving. Are they dead?

Thanks for any help

 

Are they still curled up and not moving today? The 22nd?

 

yes they still are. Its worrying me.

They are not in their eggs anymore correct? Sorry just wanted to make sure. Can you see their egg sacks? After 2 days I would assume that you would be able to see some movement

 

Yes, they will absorb the egg sacs. After a few days they will swim freely.

Some are...I can't tell rather or not the ones curled up are in the egg sac

 

Try and watch this maybe you can see if your Fry look something like his fry!

 

thanks!

yes they do look like those.
