This might be a stupid question but I have to ask:
My female cray has eggs and I'm wondering if I should turn the filter off in fear of the eggs being sucked into it when she lets them go.
She hates her hiding spot but has nested under the filter.

here is link to some info and also a couple of vids of crawfish reproducing...

-All the best

Good luck woodie... post a pic...

breeding crayfish is no difference with King Crab or the deep sea
green crab. you should wait till they are about to release from the
belly. you need a fine mesh at the suction of the filter, otherwise
they will all end up at your filter media. i have to get back for my
book but king crab need week before hatching the eggs where the mother
dies after hatching the eggs.
