Cant see the pics... I think it takes about 4 weeks or so for the eggs to hatch..
 
The pics didn't come through. There are 2 commonly available species sold as "lobsters" or blue lobsters. The north american Procambarus alleni which has a gestation period of about 4 weeks (depending on temp). And, the australian Cherax tenuimanus which has a gestation period of about 40 days (depending on temp).
P. alleni larvae look like miniature adult crays upon detaching from the female. C. tenuimanus larvae go through 2 molts before they start resembling adult crays.
It's always better to separate out the female before the larvae detach. Larvae are not very mobile initially so, a small tank is a good idea so feedings can be concentrated. It's also a good idea to add either spawning mats or pieces of banded plastic screening to provide anchor points for the larvae. Whatever you use, you can place throughout the entire water column to allow the dense hatchlings their own spot to wait for food to float by.
The larvae will grow rapidly and, therefore, molt frequently. The addition of calcium (birdcage cuttlebone for example) and an iodine supplement (aids in molting) like reef iodine should be added to aid in this rapid growth period.
Larvae can be fed the same diet as adults. I use a 50/50 mix of sinking catfish pellets and rabbit food to provide a good balance of meat protein and vegetable protein.

Are they red tips or a red stripe down the outside of the claws on the males? Red tips make them P. alleni.

mine is red stripe dwn the outside of the claws........so what name is that
 
The red stripe down the outside of the claws (males only) makes these Cherax quadricarinatus, the red-claw crayfish. I've never heard of them being marketed as lobsters in the pet trade.
Gestation period is around 40 days and the young resemble the parents when they detach. The larvae are not mobile for another week to 10 days after detaching from the female. They'll occupy the total water column provided there's something for them to grab onto. The more you can spread them out, the better. Adults are relatively peaceful towards each other but, the larvae are highly cannabalistic if not provided enough food.
 
hmmmmm uknow thier stages?
now i see is that the eggs are still underneath...
u means the eggs will detach and floating around?
it will hatch out itslf?

do i need to isolate the mother or wait for the eggs to detach then i net the eggs out to another tank for hatching? :confused:


sorry~ 1st time encounter this..hoping to get my 1st batch of small babies..heheh
