Four larvae are growing on bbs 8) As predicted,larvae seem hardy and easy to raise... :wink:
Too bad many good eggs were ruined,as the infertile mass decomposed.Happened before with my P.fridmanni,the male rejecting an infertile egg ball with some few fertile eggs.

They spawned again after 14 days.Same time and place. 8)
I started offering Oto.A to the larvae.Can´t say if they take it.

The eggs were lost on the 3rd day.They were found only on 5th day,milky and spoiled. :(
But again there were many (dead)embryonated eggs.And some empty shells,as if some larvae did hatch.

META at day 16! :D
One larva survived and kept growing.Today I found it on the bottom. :o
But it was not dead nor sick,it had settled to a benthic existance.It keeps on the bottom and behaves like a blenny.Oddly,as the adult swim in the water column like any dottyback.Perhaps they show a transitorial juvenile benthic phase?.
Not much colour yet,perhaps a slight reddish tone,plus some little black marks.

UPDATE
Days 17 and 18,it kept running madly across the bottom.Avoided some 1/2" PVC pieces furnished.
Day 19,it entered the pipes where it stays.Red colour keeps developing.
Interestingly,this species has a different reproductive strategy than the related L.lineatus,which according to Matt W.produces in excess of 1,000 eggs (which must be much smaller) and takes up to 35 days to settle. 8)

Day 20
I moved it to a grow out tank,together with some gobies,mandarins and a pipefish.
Nice reddish fish,13 mm long. 8)

New Spawn
I put a piece of 2" pipe there,but no,the male pushed it away and spawned as usual,with the egg mass hanging from the roof of a coral arch,pretty exposed. :roll:

Thank you! :D Meaning I should pull the nest early? :?

My camera ran out of batt just when my (only) juv was being moved to grow out.And it remained hidden since.
But I still can´t take decent in tank pics,we need that Will run a course for dummies in the Photoforum... :lol:

4th night and I could see lots of moving embryos! 8) Seems time brings the know how of things! :wink:
I pulled the mass into a half filled 10 gal with new water.Soon lots of larvae hatched! :shock: I gave them rots and IA NAN. 8)

Pictures of the newly hatched larvae.Compare with the previous ones hatched before term and with a larger yolk sac.

BUMMER!-Tragedy! :evil:
All larvae dead in the morning,except for two.And many eggs didn´t hatch.The bottom is carpeted with dead larvae,water cleared and is extremely full of rots.
And this is all my fault,there was just no way that all these larvae could survive in a half filled 10 gal.I should have kept about 100 larvae and flushed the rest.But I simply can not,I don´t cull,nor triage,nor euthanize.Same happened to me with Dascyllus trimaculatus,I attempted to raise hatches of thousands in vain.
To make things worse I put rots and algae way in excess,as I feared they wouldn´t be enough for all these larvae.And for the same reason I did not fill the tank,looking for a higher prey concentration.
To raise a batch of this size,I´d need to use one of these large aquaculture vats.But then,what would I do with 1,000 Labracinus? :roll:
I opened system circulation and left the eggs for another night...

Eight larvae of different sizes at 13 days.Feeding on bbs and Oto B2. 8)
They spawned again after 10 days but the egg ball was lost on the 3rd day.

And they all settled at day 22.They are getting red,and hide into pipes,no agression yet.
But they hover off the bottom,like any dottyback should,they don´t belly slide like the previous one,which BTW was never seen again.So it had a post meta swimm bladder malfunction.
The new spawn was not found in it´s place at 4th day,though it was fertile.Later it was found in the other end of the tank with the male taking care. :?

I was wrong,4 settled,one still swimming :|
They are nice puplish dotties and are starting to show some mild (yet)territorial aggressive behaviour.
I goofed with the age of the new spawn and removed it on day 3.None hatched :oops:
The male had placed them inside a 2"pipe.I didn´t know dotties could move their eggballs to different places! :shock:

Last one settled,so meta time is 16-23 days.Nice little dotties,growing fast. 8)
Some few hatched from the last spawn.

New spawn was abandoned at 3rd day.Was found loose and being picked by several fish.I rescued it and checked it.Most of the eggs were fertile! :shock:
So I incubated them and a nice number of them hatched. 8)

Hi Luis,

Do you have any problems with regards to fertility rate? Sometimes my egg balls are very badly fertilized, while other times they are fine. I can't seem to figure out the reason for this.
I love Artemac!

As you see here,fertility was 0% in the 1st spawn and then improved gradually.
I once had an orchid dotty that rejected eggballs containing some very few fertile eggs.As all the eggs are consolidated in a mass,the parent fish can not discriminate good from bad eggs,and the sight or the smell of the infertile ones must elicit the end of the brooding behaviour.
But this time the male abandoned a spawn where most of the eggs were fertile... :?

UPDATE
Now I have lots of thriving larvae,with guts full of rots! 8) 5th day.I hatched them in a 10 gal with rots and greenwater with NAN (live).

Update:Bummer!
A juv.A.perideraion jumped into the larval tank and ate most of the larvae! :evil: It was such a nice batch... :cry:
Starting with bbs and open circulation today.
