Overactive males when a berried females eggs hatch..

So, I can tell when a female has had her eggs hatch, as the males all go into over-drive, swimming around like they're on crack; the females are not to be seen.

Does this happen to anyone else? It last's for about half a day...

For me, that is typical behaviour when a female moults, All the males buzz around trying  to find her as she is receptive to mating at this point. Even my zebs do this. I thought something was wrong with the tank as all the shrimp were buzzing around everywhere. I found two berried shrimp a couple of days later. 

I haven't seen it happen when shrimplets have been dropped.

It hasn't happened in the past, and I've only noticed it since getting shrimp again about 4 months ago. Its a regular occurrence, I feel it may have something to do with the 10+ Ember Tetras I have in the tank. Maybe some kind of protective instinct?

I've never had fish in with shrimp, so it new to me.

U will find although your tetras are small they may take a small nip at your shrimp

Maybe the fish think its feeding time and start nipping at all the shrimp whenever new shrimplets hatch?

I've seen them nipping and I'm sure they've taken a few shrimplets as well! Lol

On another note. I've got a juvie some what  rili female from who's just saddled. Both parents are not rili's in any way.  I'll be separating her once berried

      Hi new shrimp owner here. I’ve read and done lot of research. I’ve had them for only a short time before the 3 females I have became berried all at once. One is an orange and she has a full batch of yellow eggs. I have a clear, with red saddle and tail and a little yellow. She has a small 4 eggs batch (assuming because she’s new to the tank or a new mom) and then this beauty (as seen pictured. When I read about egg color they are yellow or green. Can someone tell me about these blue eggs? The male is all black.

      Okay, so the title pretty much says it all... One of my berried tts just moulted, and she left the eggs in the moult. What happened, and why? 
      I'm going to try to save the eggs with some sort of extraction, and I'll be very careful. She was pretty far along. I think I'll use the net over bubbler method. Does anyone have experience with this, and particularly the extraction? I won't do anything until I have some idea to go off. 
      Thanks in advance.

      Oh and the moult is under like 2 hours old. Wasn't there when I started watching a movie, was there when I checked back after.
      Going off this video: 
      Hoping the process will be similar.

      I have been trailing this product for about 8 months now:
      Ingredients: Lactic acid bacteria, crustaceans calcium, reduced maltose, mulberry powder, yeast
       
      I cannot argue with the fact that it increases my berried ratio among females after feeding. I sceptically attributed it to the protein component only initially, but trialling one tank on protein- high Ebita Breed Hinomaro bentou and another tank on B18, I still find B18 has a more pronounced effect on fertility.
      Whether it is potentially the Lactic Acid Bacteria strain used, the highly absorbable form of calcium used, the digestability of the yeast protein or a combination of all above, it appears to work.
      Dosage: Once a week, small amount.
       
      Highlights:
      - very little is used, so it lasts a long time as it is very concentrated.
      - the shrimp are attracted to the food supplement when put in the tank.
      - it completely breaks apart into a fine particle mush so that all shrimp can have a bite of the small portion dosed
      - it indeed does increase berried rate
       
      Concerns:
      - not available for purchase in Australia yet. Available in Japan, Singapore, Hong Kong.
      - possible water contamination potential if too much is dosed in nano tank.
