Buyer's choice between 1/4" (not recommended, but you can get a LOT for the same shipping cost
) and 3".
They berry either once per molt or every other molt, i believe it's once per molt.
Roughly speaking that's every 20-45 days, possibly shorter, possibly longer. When i only had one and could keep track it seemed like once a month, as such yours
should berry within a month of arrival, but it may take two if they just did and i couldn't tell, or if shipping through them out of whack.
I have two (i think) that are berried right now. If you want to pay a discounted version of the standard berried crayfish rate (usually 4x or so, i'll go for 3x, that being $15 which is still under most aquabid prices till i showed up) i could ship you one, but i can in no way guarantee that the eggs would survive the process. So while i'd be happy to get more money per crayfish, i can't actually recommend it.
