Try cookie jars with a diameter of around 8". The wooden airstone at the side near the bottom creates a better circulating current. If the base is too wide it does'nt happen.

At the moment, I have swapped to the wooden airstone, but its ancored to the heater on the bottom. this put the airstone in the middle of the RBT.

Do you mean, move the airstone to the side to get a circular flow around the circle of the container or do you mean a circulating flow bottom to top?

Yes airstone to the side to create a kreisel uni-directional flow somewhat. Those airline suction cups work just fine. Wooden airstone all the way to the bottom at the side of the cylindrical vessel.

After taking a break from these for a few weeks, I have collected a spawn on each of the last three nights. They were all smaller spawns and I have them in the same RBT. I siphoned the bottom and exchanged 80-90% of the water yesterday and will continue to do this regularly.

Here are some photos from tonight for the latest batch of shrimp. I think that this is the first time I have some shrimp that appear to have 5 sets of legs and have lost their paddles. Again, photos are not great tonight, the little bugger did not want to stay still I really like the eye's and how they look. It reminds me of an insect eye. Am I right in thinking that this shrimp is at Z9 or Z10 in terms of development? If some one who knows could let me know that would be great.

Cool! How old are these ones? What type of vessel and maintenance are you doing these days?

Went back to my origional method, much like with the clowns Started with some rots, green water and nhbbs, added more nhbbs as the got low (tried to add small amounts) Container is a 50l RBT with a regular air stone. Started with 10-15l bloodstock water, added ASW and RO water at about 1l per day. Occasionally if bubbles were remaining on the surface I added 0.5-1ml of amguard Batch has hatched from 23-26th Jan, so about 16 days old. Removed water sparingly over this time 2x25% changes. On checking them yesturday, there appears to be a significant die off again. Last night I could only find about 30 left. I think this is because I let the water and RBT get too grubby.

after draining the RBT today only 5 were still alive and these did not look good. I have put them in with the Lysmata amboinensis on the hope that the greater NHBBS in the bucket will encourage them to hunt. Not really expecting them to make it, but its worth a try.

After reading Whys Alives journal on Sexy Shrimp, I noticed there was lots of talk about damaging the shrimp larvae by handling them via siphon or maybe even pipette. I'm wondering if that might be contributing to my deaths. What do you think? How do you go about the waterchanges? I have just been slowly pouring the water out into a shallow tray and then pipette each larvae back into the culture vessel. So every single larvae is handled everyday. Also, in the mornings I siphoned the bottom of the vessel, and would siphon out a few larvae each morning which would be pipette'd back to the culture vessel. Now I think if it there were always a few deaths everyday. I wonder if those were the larvae that got siphoned out during the morning clean? Also now I think of it I siphoned the vessel out into the tray with a 1/2" hose a few times near the end of the life of my last batch...maybe that was the reason for the sudden die off over 24 hours? Hmmm...what are your thoughts?

It's possible, I have associated the losses with me not cleaning in time. Another way to look at this is that I have been too rough with them when transferring/pipetting. As there are a few instances now where ivehad big losses 1-2 days after counting them. On my next batch I'll do 1/2 in a rbt attached to my breeder set up and 1/2 in an isolated rbt and see if I get a different/better result. I'll run just a trickle of water change to aim for 1-2 changes per day in the tub. In terms of water change the latest lot I went back to 25-50% changes. So I'll do this again with the isolated batch.

I did 100% waterchanges everyday, didn't skip a day with the last batch that got to 10 dph or whatever it was. That was also the first time I started using RODI water as source instead of treated tap water. So I'm still not sure if the waterchanges were of any benefit. The water I am using has been mixing for several days, but is not cycled in any way, no ammonia detoxifiers added, just salt mix. This new batch I'm going to do daily evening 50% waterchanges, morning bottom siphoning. Maybe the 100% changes are too harsh. I hope you don't me sharing my ideas/plans/doings in your thread. I post in your thread more than in my own journal. Oops.

14dph 5 shrimp still going. I have moved these from the RBT to a small glass tank. The tank has a heater and an air line for current. hoping that I can keep a better eye on them this way.

I put my latest batch in a 5 gallon aquarium with heater and air stone too. Most of them lay on the bottom of the tank, and I've had significant die-off (~50%). I haven't done any waterchanges, and have pretty much just been ignoring them because I've exhausted my ideas for now. I'm kind of done with these guys until I can figure out a new method as my current methods clearly have not been working. I'm working on building upwellers...my new plan of attack. Good luck with yours.

I have collected a couple of spawns in the last few days and am going to give these guys another go. Will see if I have anymore success this time around.

Well its day 15, 16 and & 17 for each of the the three batches and they all seem to be still going strong. Im changing 20L of approx 35L every two days by siphoning the bottom with an airline tube, then replacing the water with a dripper over about 2-3 hours. Im keeping the NHBBS fairly high in terms of density and they are peppermints are feeding very well. PS. Knock on wood, here is hoping that this post is not a bad idea
