The idea is fantastic, but many breeders use egg tumblers. I believe its to equalize water movement around the egg. Maybe the area of contact with the sponge is the area of staleness. Perhaps a more tumbleresque design would work better?

Is there any reason I couldn't put the eggs within the airspout (for lack of a better term) on top of the sponge filter? Because the spout sticks out of the water so it's not like they'd float away. Of course, might be a rude awakening when they hatch...of course IF they hatch. Cause if someone thinks that's a good idea I can move a cluster of eggs to that spout. Had another egg turned orange I had to remove

I'd say stick an egg there it you think it might be worth it.

I would be concerned about the eggs sticking to the side of the plastic because the bubbles may push it out of the water and stick it to the side.

Well then I'll just leave them as they are. I'm sure this won't be my last opportunity to try all the different methods. Unfortunately.

Yeah I made an egg tumbler....but the netting on the bottom was too big and snails and other shrimp were able to suck out the eggs from the other side :\

I just noticed aren't sponge filter is the dirtiest place in the tank? So maybe the eggs are trapped by all kind of stuff in the tank.

This is a sterile tank, NOTHING is in it, the sponge is a 'virgin' sponge and has never been used and the water is straight remineralized RO water. So to answer your question, in this situation no

On a side note, just like Pasture's experiments way back when, bacteria and life is everywhere. So the tank technically isn't sterile. Hence the fungus that grew on that poor eggie :/.

True, true...but it never looked like fungus (not that I'm used to seeing). The egg started changing shape before I saw anything on the outer side happening. Doesn't mean it wasn't fungus, just worth noting

Ah true. Fungus wasn't the right word. It looked like some type of organism that feeds off dead things, I doubt it was appendages of any sort ;(

i didnt read through the whole thread but this "splitting" is not normal and i think the egg/shrimp is dead.
the egg stays the same size the whole time.

in the coming weeks i will be photographing CRS eggs under a microscope as they are developing, ive done this before last semester without photo-documentation, just observing. this time i will photograph and take videos for everyone to enjoy, you can see many details such as individual pigments (red pigments and white pigments in the CRS), legs, tail, organs, and cell-like structures inside the egg. you can even see its heart beating.

head up for an exciting thread coming soon!

Yeppers, and that's another reason I wanted to photograph it. Either it was going to go to the good side or to the bad side and it seems once the split develops that signifies the death of the egg. But the interesting thing is, as they die I try to separate them out and remove them. Well, they have tails and legs and antennae, just the front half is still 'egg shaped' so I'm wondering if it's the outer 'shell' of the egg (for lack of a better word) that is dying. I'm losing them left and right now but only the eggs that were in clusters I couldn't separate. So fungus or microorganism or whatever it is, seems to attack all eggs in the cluster (like a fungus but doesn't appear to be fungus). In hindsight I possibly could have been better off if I would have separated them into individuals but it's more than slightly difficult without damaging the egg...at least for me it is.

Would love to see this and also know how you are getting them to hatch in the first place
