THX @all :)

@kuza: I follow you and your thread! :D

OK, now I have al little bit of time, to describe my new attempt to rise little hermits.

First of all I changed something at my set-up. I ordered algae (nannochloropsis), which make a 'nice' green water in my kreisel-tanks and it's getting greener every day. The tank, which you can see at the right side is not in use, because it's not working well. Therefore the larvae are only in the two kreisel-tanks inside the big tank left:
Image

On July 15 I got the first larvae and a day later nearly as much:
Image

Every day I spend an hour or so to clean the tanks. And I made it efficiently this time!
I use a tube to run out the water in a bucket. In the bucket I have two different sieves to sort hermit-larvae from artemia-larvae:
Image

Then I put the hermit-larvae into a plate to sort the dead out. This plate is rotatable! That's nice, because if I rotate it a while, all larvae will swirl into the centre.
Image

Now I have to wait a few minutes an the living larvae are swimming to the left side. OK, they don't know where left and right is, but there is more light. ;)
Image

Image

I take a big pipette, catch a couple of hundred larvae an put them back into the kreisel-tank. And so on,...

And now some pictures of the development till now:

I love your interesting method of cleaning the tank, such a good idea IMO!
They look fabulous and looks forward to seeing next weeks update. :)

Also, have you considered not using algae? I've read a lot of literature that says it will produce a negative amount of oxygen overall and suffocate the fish fry.

I've tried it the last four times without algae. And the last time I had one kreisel-tank with algae for something else. Because of the huge amount of larvae I've put some hundred in that tank and they grew so well, that I decided this time, I will only try it this way.
Meaning all caught larvae in one tank, with algae and many artemia each day. Works well till now, and I'm at day 12 (11) now. I'm losing 1 to 10% each day. The death rate is a little lower compared with the other efforts.

Same here, I think it's too cold and still too much like winter.

One big news! One is literally, because I have one little hermit crab, form the last breeding, which made it on land a few days ago!

Sorry for the late report, but I was al little tiered of posting in every forum, where I'm a member, to then tell all other members after some weeks, that all larvae in the end died.
So I waited since one finally made it on land.

Review:
Day 1: About 1000 larvae, maybe Violas.
Day 2: 565
Day 3: 362
Day 4: 301
Day 5: 296
Day 6: 288, first Z2-changes
Day 7: 288
Day 8: 268
Day 9: 243
Day 10: 222
Day 11: 166, first Z3-changes
Day 12: 128
Day 13: 99
Day 14: 28
Day 15: 26
Day 16: 26, first Z4-changes
Day 17: 24
Day 18: 24
Day 19: 24
Day 20: 24, first Z5-changes
Day 21: 21
Day 22: 20
Day 23: 19
Day 24: 17, first megalopa (dead!)
Day 25: 17
Day 26: 14
Day 27: 10
Day 28: 9 larvae, 1 megalopa
Day 29: 4 larvae, 3 megalopa
Day 30: 3 larvae, 3 megalopa
Day 31: 3 megalopa
Day 32: 1 megalopa
Day 41: shows interest on houses
Day 47: found a fitting house
Day 50: first time on land!
Day 54 (today): everything seems ok. :)

Older larvae:

Megalopa:

Today:

So far for this little crab.

An now the next surprise: My PPs spawned three days ago. OK I was sure, some of them would, but.... all of my females did.
Therefore I have round about 15.000 to 20.000 larvae right now. :pull_hair::

This is one of two new kreisel-tanks, with some thousand larvae. You can see the second one behind:
