30 Hours

I cannot seem to find the edit option to add more photos.
53 hours - You can clearly see these guys moving in the eggs

 
126 hours - Hard to tell from the photos but they are starting to look like their parents

 
Not sure if I am going to pull them or take the skimmer offline for a few days and see if they settle in the main tank.
 

Awesome pics!

Here is a poor quality video showing the movement at appox 50 hours. Much more movement inside the eggs now.

148 hours

Neat pictures. I like the pink background.

These guys are really taking shape.  However there is a new attachment to the eggs.

 

Wow, fantastic pics! I had these guys spawn for me a while ago, and I surprisingly noticed about 20 babies on the rock 1-2 weeks after I noticed the eggs. I have no idea why they made it, but if it helps, I did not have a skimmer on that tank. It was just a biocube. Good luck

 It appears to me they have hatched from their eggs and are moving around. But they are contained by the larger membrane if that makes sense. Not sure if they are eating their way out of just developing more before leaving. 
 

I will be following... have 2 types of sp. in my tank - both of which have been laying eggs (looks like balls of spaghetti - not on the glass..)... but not sure if they are fertile? Great pics!

Ok I think I found them. The only rock in the tank without hair algae I cannot get a good picture atm but I am working on it. I can clearly see oral tentacles when zoomed in.  What do you guys think?

I love your photos. The veliger stage (148 hours) with the pink background is fantastic! Good luck growing them up!

Amazing photos!  Any updates on them since?

Finishing up my battle with Hodgkins, 30 more days. I will try to update ASAP.

Oh, heck. Good luck! Let us know if you need anything....

All of those pictures are stunning.  Hang in there and keep up the great contributions as you're able!
 

Hope it all goes well.

Keep growing that hair algae! I had a bunch of these that bred for me back in 2005, and at the time the tank was relatively new and had a good amount of food for them. Once the hair algae was gone, the nudis weren't too far behind that. Just some advance warning in case you weren't prepared and wanted to keep them! There's always someone in the hobby with hair algae.
