tank is a 10g, she is by herself. she has a cave and lots of empty walking space. im not sure how old the thing is. its probly full grown thoughI'd look to the tank conditions. Is the tank crowded? Does she have enough placed to feel safe? Is there anything harassing her in the tank like shrimps or other crays? I'd watch her carefully when she berries up again. I definately wouldn't take the eggs from her--she could get injured doing that. Sometimes younger crays are not successful with their first couple of berries. Give her time is my opinion if everything else inside the tank is set up properly and she appears safe and comfortable.
