For the last few nights I have been expecting the eggs to hatch.
They are very plump now, with the swimmerets now no longer able to close neatly. The underside of the shrimp looks disheveled.

Re:Breeding Journal, Species: [Lysmata amboinensis] - Thursday, December 22, 2011 2:08 PM
Excelent view of the limbs which allows a description.Zoea 1,the first stage,has two pairs of limbs called maxilipedia (MP2 and MP3).But each splits in two "legs"called endo and exopods.Looking as if there are 4 pairs instead of 2.In this pic one can easily see how endop and exop stem from the same root.
So we have from the front to the rear:
MP2 end.-The short one.
MP2 exop-
MP3 end.-(coloured point)
MP3 exop.
endop of the right MP3 is bent to the left side of the larva.
And we also have a clear view of the antennula (A1) and antenna (A2)

New hatch tonight of about 100 fry.
 
This will be the last hatch until I get some more brood stock.  My largest shrimp has now killed two other cleaners one at a time over (I think its the large one doing the deed).
There are some other shrimp in the same tank.  This pair has been together since may last year.

Re:Breeding Journal, Species: [Lysmata amboinensis] - Thursday, February 9, 2012 9:49 AM
well my estimate of 100 fry was way off.
tonight in cleaning out the black bucket they are in I stopped counting at 250.
So either they are able to self duplicate or I cant count.

I'm finding raising these little aliens really exciting.  Every time I take photos of them, they are different.  Its like a little surprise every couple of days.
They are 6 DPH as of tonight and seem to be going strong. 
Even though Im not getting any through as yet, with these or the peppermints, its still fun and I appear to be making progress slowly.

Again your pics are outstanding!
You focused on the antennae and we can see a flagellum between A1 and A2 which shows only briefly,in Z2.Amazing!

Re:Breeding Journal, Species: [Lysmata amboinensis] - Thursday, February 9, 2012 11:38 AM
Thanks Luis,

I need to learn more terminology ...

In the second shot there are what I assumed are gills that are external to the body as the were pulsing as the shrimp was sitting still.

These have a red base with white fluffy ends that pulse, like a breathing action.

Each of the photos are of different shrimp fry. The middle one was "bulkier" than the other two to the eye, it's what made me pick that one, it also looked red in the body. The other two were lighter and pail yellow to white to the eye.

Under the camera this red colourful was not apparent, I checked a number of fry with the same result.

No,these are maxillipedia,not gills.Anatomy of larval appendix is a little complicated.See my threads for a description.Yes,they keep them moving like bringing water to their mouths.
This is the 2nd zoea and only during this stage,we can see this flagellum between A1  and A2.Hard to see and a nice photographic document!

Re:Breeding Journal, Species: [Lysmata amboinensis] - Sunday, February 12, 2012 10:08 AM
well its another big bucket of fail.
They are all dead again.
 
I keep making stupid choices with these guys and the peppermints, like "that bucket looks a bit dirty, its late so Ill clean it tomorrow".  Then I forget to clean it the following night and then they are all dead. Grrrrrr.
 
Its my own fault, if I cleaned it straight away, it would be fine.

Collected a large batch of fry from my reef tank tonight.  This is from one shrimp, the other released a similar amount three days ago.

 

 
How great are chads larvae snaggers.  They make it so easy to collect shrimp. Cheers

Re:Breeding Journal, Species: Lysmata amboinensis - Exploding Heater! - Friday, August 9, 2013 3:52 AM
 I had a bit of a horrible experience a couple of nights ago with a heater exploding and demolishing a tank.
 
The tank had been dry for a couple of weeks, everything was unplugged.
I removed everything from the tank and gave it a good clean, including the heater then used the heater to keep the fry warm in a 5 Gal salt bucket whilst I added water to the tank.

Once it was ready I unplugged the heater, put it into the tank, added the fry to the kressel in the tank and then turned the heater on.
 
Initially the light came on, on the heater and then flickered.  Then it looked like is started to ark.
I turned off the power to the heater, as I did so the ark got really bright and then the heater exploded.
 
The tank is 6mm glass and two large holes were punched through it.
 
I have to say, this was one of the scariest things I have had happen.  Massive bang, water everywhere, nasty smell and the power shutting off to the sound of water poring out of the tank.
 
The remains of the offending heater (ironically the brand is listed on one of the shattered pieces, so Im not sure what it was.  I do have another one somewhere so thats getting removed).

 
Whats left of the tank and my kressle


 
 
A few days later the fry are still alive now back in the 5gal salt bucket with another heater, I was expecting them to be dead, but it looks like I should keep feeding them and put them back into another tank.

Re:Breeding Journal, Species: Lysmata amboinensis - Exploding Heater! - Friday, August 9, 2013 8:50 AM
Wild.  Arc, *snap*, lights-out, then nothing but the woosh of rising water.  That sounds a bit like being on board a ship wreck.  Of course, to be literal, it was a sea vessel that ran a (electrical) ground.
 
Personally, I prefer titanium heaters.  You really should post the brand.
 
Hope it all works out!

I had a hunt around for the other heater I had that was the same.  But it looks like it was one that failed a while ago and wasnt heating.
I have no idea on the brand or even how old it was.
 
On the positive side, the batch of fry is still going.  1/2 have been put back in the kressle in another tank and the remainder are still in a 20l/5g salt bucket and doing well.

Well after all of the pain these guys have gone through they are still going.  There are only about three left in the kressle but a heap in the 20l salt bucket.  The pics are from the salt bucket ones.
 
Something that is interesting, is the tail of these.  They are spindly rather than joined like a fan.  Is this normal?

Re:Breeding Journal, Species: Lysmata amboinensis - Exploding Heater! - Tuesday, January 21, 2014 9:55 AM
Collected a new batch of fry tonight.  Something that was a bit weird was that some quite yellow and some only white.  For the time being I am assuming the white ones may have been peppermint shrimp.  They seemed larger and were all white.  Also collected were five Amphiprion ephippium that hatched at the same time, these were left with the shrimp fry.
 
In total there would be between 600-800 fry, it looks like the biggest batch I have got from this pair ever.
