Hi, New member!

I have a 20 gallon tank with a an electric Blue crayfish (name is Crush) and a platinum white (name is Axe), they are both females. Crush is younger and sometimes Axe bullies her at times (ripped off a claw which is now growing back)

Anyway, I noticed this morning that Crush built a wall up to the opening in her den and closed herself in, it was the second time (2 days ago was the first),that she's done this. I took the wall down the first time. I'm wondering how she will eat? Will she just break it down and come out when hungry? How long will she be ok to stay like that?

Has anyone else seen this type of behaviour?

Any info would be appreciated!!

Croeso welcome to fishlore butty
Yes I've had the same thing twice the first was when she was berried and stayed in there for weeks I always dropped food close to her hide at lights out, she did appear now and then but always blocked herself back in. I think it's natural, the second time was when she was moulting so I don't think you've anything to worry about

Thanks Richie. I'll leave Crush to her dark place and keep an eye out. I know they like to dig and move the substrate around, but hadn't ever seen this behavior before.

I've had Axe (platinum white) and Smash Bright orange) for almost 3 months now (Smash is in her own 10 gallon now, but was with Axe previously in the same tank that Axe and Crush are now together in) and neither of them had done anything like this.

Mine not only thinks it's a bulldozer redecorating the tank but blocks his cave entrance and will dig a big hole and after he moults he puts the excolital in the hole and covers it until hes ready to eat it something I've not seen in other crayfish

10"!! That's huge, I think these guys will get 4"-5" max.

But, beautiful colors on the red claw.

I wish I could figure out a way to get myself a cherax pulcher. Proving quite difficult, unfortunately

Hard to tell if she has or not. The den is quite deep and I see into enough from the front. When I clean next I will lift it up and check.

But, she does look great. I'll feed her something extra special tonight

Yep. I'll keep an eye, but based on how she's acted before she looks like she's poking around for food. We shall see!

Anyone recognize this behavior? These are both female, or at least I'm 95% sure they are...

I hope I didn't post too many pics? Just trying to ensure there's enough photo evidence to display the situation

I think the female has to be on her back for them to breed..
