FASCINATING egg development:) Update 3/3 Post #79!!!!

UPDATE : This first series of photos shows the death of an egg....so ignore my excitement. However, read on through as there is more


So I lost a berried CRS two days ago and despite having ZERO luck hatching eggs artificially in the past I decided to try a new method brought to my attention by a friend. At any rate, I've been photographing them every day so I can track development or if I lose any. I took a photo of the egg closest to the tank wall this afternoon before I went to the gym. Here is that photo. There is another egg right behind this one that is somewhat visible.



And this is the same egg after I returned from the gym 4 hours later.



It has completely split now and starting to unfurl which is just the coolest friggin thing ever to me. Maybe folks have seen this before but I haven't. These were due to hatch anywhere between tomorrow and next Thursday (28 days to 34 which has been average on my CRS fems).

Just wanted to share and will continue to document anything I can.

Eyes appeared in the eggs about 2 days before the female died. She stressed herself to death IMO. I notice once the eggs develop eyes the females get very still and don't fan as often so I wonder if the eggs begin to somewhat move on their own. And right before hatching the eggs look like they've doubled in size and if they all split like this that would explain why. I'm so tickled I can't stand it. I truely hope they hatch as this was one of my favorite CRS I had, beautiful red legged nice quality girl. Seeing this split happen though I'm hoping this little fella will hatch soon. This is the only egg out of 20+ so far I notice doing this. The others have eyes, just haven't split like this.

Nice pic! Never thought you can lay them on a sponge filter like that.

Can't take credit for it, Soothing Shrimp sent me a video a few weeks back in Japanese. We couldn't understand it but could at least see what the guy was doing. Theoretically it makes sense but I won't hold my breath because my 'hatching' plans haven't worked in the past.

I don't know if it's so much as mad scientist as it is 'desperate shrimp keeper'. LOL! If I could just find SOMETHING that would work I would feel better about it. I've done the fancy hatching nets, simple nets, moss with airstone under it and none have worked...fingers crossed!

Ravengate and I brainstorm back and forth a lot. We tend to build off each others ideas.

It should make sense because the fanning of the eggs runs water over them to deliver oxygen and hold off fungus.

A sterile sponge filter in a sterile tank draws the water over the eggs like "mom" and should do the same thing.

If it works like we hope it does, it should provide a way for hobbyests to save clutches of expensive shrimp when mom passes away berried. Jaime had the opportunity to put this into effect, so I- along with everyone else- am waiting anxiously to find out what happens and congratulate her if it works!

As far as I know, this is the first time anyone has documented this.
