Dixon1990 Posted November 23, 2008 Report Share Posted November 23, 2008 Do not let them go , this could introduce disease etc into the waterways, My suggestion is to givethem away to people as [pets Quote Link to comment Share on other sites More sharing options...
enzoom1 Posted November 23, 2008 Report Share Posted November 23, 2008 Yeah like dixon said don't let them go. You would probably be better off (if you want to keep them) putting them in a another tank to raise them. I'm not sure about how the parents look after the babies because they might look after them? Btw, are you talking past tense? as in, you used to have your tank? Quote Link to comment Share on other sites More sharing options...

ninjafroglet Posted November 24, 2008 Report Share Posted November 24, 2008 How big are the babies? As far as I know the eggs are held underneath the mothers tail until they hatch, and then as small koura they cling onto the underside on their mothers tails until they are big enough to fend for themselves.

Stella Posted November 25, 2008 Report Share Posted November 25, 2008 wow, congratulations! Firstly congrats for being able to keep several in the same tank without them eating each other! Crayfish reproduction.... They mate fact to face. (random trivia ) The females hold the eggs under thunder their tail, externally. ('in berry') The northern cray (which presumably yours are, if locally caught) stay in the eggs over winter I think, quite a few months anyway. The babies hang on to the mother with a special hook on one pair of legs. After the hook dissappears (after the second moult) they leave the mother. There can be a long time between the first and last hatching, and between the first and last baby leaving the mother. Everything is temperature dependant. They grow faster if it is warmer (within the paramaters of a coldwater habitat, they should NOT ever be put in a tropical situation) I don't know if the babies are at much risk from the adults, but due to the adults inclination to eat each other I would suspect there is risk. However if there is plenty of cover they might escape detection... As the others said, don't release them. But :bounce: :bounce: :bounce: for having bred them, albeit accidentally!
