Moved from salt dish to growing tank (fingers crossed)
I have managed to track down brine shrimp eggs online and they are being expressed to me ;) My local aquarium shop was brilliant and has helped me out with some powdered fry food to get me through, the powdered flakes I was making fouls the water pretty much instantly so this stuff is much better. picked up some ammo lock (while I visited every pet/fish shop within 40km of where I live in my search for brine shrimp eggs) to keep on top of the ammonia build up from the feeding. Twice daily water changes so far and all appears good. wish me luck

Aw shucks thanks
At this stage I have no idea which male & female are the parents, as like the previous times its like hey presto bowl full of babies :) I can not take and creds for breeding, they've done it all themselves, I've merely been the spectator of happy crabs.
I will take some pics of my crabs shortly and will post them so you can see for yourself. They were tinies when I purchased them & now they are a pretty good size. I used to have the circle thing somewhere for measuring them, must look and print a new one.

welcome stage 2 zoea!

Ive learnt a lot over the last few days about C. Variabilis
#1 non feeding zoeal stages 1 & 2
#2 takes only 6-7 days to get to megalopa which is stage 3
#3 once megalopa they become cannibalistic (but will consume tropical fish flakes)
#4 they do not need a shell to metamorphose
#5 metamorphosis takes 1-2 days after digging down
#6 30% survival rate at 30 degrees celcius (significantly reduced at 25, just like our adult crabs, very sensitive to temperature)
#7 the whole aquatic stage lasts on average 25 days!!!!!!!
Alan W. Harvey who wrote the section abbreviated larval development in the Australian hermit crab ceonobita variabilis McCulloch (Anomura: Coenobitidae) pg 196 - 209 in the journal of crustacean biology Vol 12 no. 2 raised C. Variabilis larva to land dwelling stage from females heavy with eggs taken from the beach in darwin NT. The above information comes from this extract.
Well Mr Harvey Im happy to say my females have been in captivity for years

I will be super happy if I get 1 to land :D

perhaps this is the first step in securing our wild populations, Captive breeding would significantly change the hermit crabs life here in Australia (obviously a diverse gene pool would need to be considered so the species don't develop other issues due to inbreeding), they are harvested off the beach, the government stopped them from being exported internationally/exploited years ago. Once they cease being a throw away pet ($10 AUD) I am certain that the level of care & knowledge required to keep one of our magnificent land dwelling crustaceans as pets will lift drastically and the survival rate will increase. This raises a new question.... What should the purchase value of a captive bred crab be? Considering expenses related to breeding. how many of you would prefer to buy a captive bred crab rather than a harvested wild crab? I know my answer, whats yours?
I for one am looking forward to producing a care sheet (with all of you with Aussies helping please) which will go with any of my captive bred crabs, if & when I get to that stage ;)
who knows..... one of us may have our captive bred crabs for 34 years plus 8)
Oh and if one more person says to me its just a crab.......... Look Out :@
