It passed the 143 days mark (time at which the other one settled)and it´s still a larva.But it is strong and has grown to full size,about an inch,so I expect meta soon.
Reasons for some delay:this survivor was the smallest of it´s group,and it lost the pp5 legs recently.They have regrown though still not to full size.
The larva is molting every 5 days.Last molt shows chelae (claws)well developed in pp1 and pp2.Uropods show about 100 setae.There were about 60 setae previously,so I think that amboinensis larvae don´t "mark time"but keep developing thru subtle stages some specialist will someday describe.

Which didn´t pay off in the long run<a href=showthread.php?s=&postid=10840486#post10840486 target=_blank>Originally posted</a> by billsreef
You have a lot of patience
The larva was found dead on day 151.Length is 28 mm.Uropods have about 120 setae.Unfortunately the two first pairs of pleopods were damaged,so I could not confirm A.Rhyne´s observation that this species shows development of appendix masculina in the last larval stage.

how are you doing Luis....how many molts are necessary for a full regrown pp5?? L. bahia needs two molts...and some other ones as well....

I just got in 4 new cleaners since the ones in my display didn't make it through a dino infestation...or they are being eaten. Anyway, two came in with full egg loads. I put one of those in the fuge, and one in the QT.
Noticed today many larvae in the QT. I promptly shut down the skimmer, powerheads, and HOB filter. Put in an air stone one low. I know that this morning the QT temp. was at about 84F.
I have been dosing small mounts of phyto and plan to do water changes through a seive. If I have any luck at all, I will be sure to post. SInce most of my reading has shown that it is extremely rare for them to make it to adulthood, I do not have false hopes.
I have been lucky before though! I take it that it is recommended that I remove the adult shrimp? It appears to be minding its own business in one corner of the tank so far. The larvae are swimming around and appear to be interested in the phyto.

are you raising them in single batches or are you trying multiple generations at once? incase you fail at one batch, you could have a second batch only days behind the lost batch.
what your doing is what this hobby is all about. someday captive breed shrimp will be as common as CB clownfish. maybe even morphs! imagine someday a cleaner shrimp thats black instead of red.
in the freshwater shrimp category, new morphs have been created and are very popular. fortunately, freshwater shrimp can sometimes be mass produced in a home aquarium with no effort.

well at lights on this morning I had nearly 100% mortality, so that doesn't even qualify as an experiment. Barely a fart in a hurricane if you ask me.
I appreciate the encouragement though, and now that I know more about their life cycle, I will be better prepared next time. I will rig up a round tank and try to get the circulation better. I think they perished because the temp. got down to 77F last night.

could you provide some photos of your culture station? im interested to see what the tanks are shaped like and how you have them set up. some day in the future id like to attempt this.
also, you said you were feeding baby brine shrimp, and something else. have you thought about cyclop-eeze? quick look on their site found a section on saltwater shrimp (i know its not meant for ornamental shrimp) and thought the same results could cover the cleaner shrimp. there was a graph (go figure i cant find it right now!) that showed a double in survival when cyclopeeze was supplemented into the diet.
well i dont know if you had tried this food yet or not, but being that your in the hobby i assume you have heard of cyclopeeze.
hope this helped!

77F doesnt seem like a temp to be worried about (i could be wrong), because i keep my reef at least 75 for winter and let it creep up to 79-81 in summer. i would feel safe to guess that 77 is safe. did you test for an ammonia spike?

well maybe so. All for naught though, and I nuked the tank last night by accident anyway. Tough week for the QT/Grow-out tank! I really should get it on a controller. Just got back from a local reefer's pad where she has several hundred baby clownfish of various types, about 50 baby seahorses, and recently settled pepermints. Her kitchen area is like a breeding lab with over 20 tanks for various breeding stages, brine shrimp and rotifer production, etc.

will you be making a guide for this? or a list of things to do and not do and how you did things?
even a photo of your setup is worth alot

Read this thread from the beginning, Louis has been quite generous in taking the time to document it all here
While this thread deals more with larval development than with culture details (which were explained elsewhere),some relevant aspects were discussed here.Larvae reached Z10 at 35 days.Hydroids showed again and I immediately scooped all the 60 larvae out and scrubbed the tank clean.They took this rough treatment pretty well,i.e.no complains were heard
