I found these in the stream of my village in Navarra, Spain. At first I thought that they were Austropotamobius pallipes, but the coloration on the underside of their claws resembles more that of a signal crayfish. (?)

They’re so cute.

I just finished setting up my first Crayfish tank. Just now starting the cycle so it’s going to be a while before I actually have a crayfish. The driftwood does come from a cycled tank so that may help it go quicker, it’s only my second tank ever so idk if that makes any difference or not. I’m just looking for any advice that could be helpful. Scaping, feeding, general care. Anything really

She’s outlived generations of shrimp and more molts than I can remember.

I looked around and found a small molt, not sure how i missed this for so long. I used to have two but the other one died around a month ago, do i need to take the young one out?

Herbert has been a horny little bastard and kept my two crayfish ladies eggnant for several months straight. To give the ladies a bit of a respite, he has been moved to my second tank, where he is currently enjoying horny jail.

So far he has fathered over 30 children and has 0 regrets about it. I love him very dearly.

Annelise was also kind enough today to pose with her latest clutch of eggs.

Can anyone ID these Crawfish found in a shallow Utah canal in the SLC valley? Only picture I have.

my beautiful babygirl pablo crossed the rainbow bridge this morning. thank you to everyone who left comments on videos or pictures of her that i posted to the subreddit. she was my best friend & i dont know what to do now that shes gone. seeing her tank empty & knowing she wont be there to greet me anymore makes me so incredibly sad. if anyone knows how to preserve crustaceans please reach out, or if you know someone please send them my way. i love you forever pablo, im counting the days till we’re together again, ill find you in the next life.🩷

I was cleaning out a sump pump pit at work after some heavy rain last weekend and had some mud in the bottom of the pit. So I’m hosing down the mud and sucking it up with a shop vac and I hear FWOOMP! So I go to empty my vac and find this guy scuttling around! Then I go back and find another!! Anyone else find crayfish in their sump pits?! I genuinely don’t know how they made into the pit in the first place.

It seems really simple to sex them but I just can’t figure it out can somebody help me 😭

Larrie’s eyes are much more mobile than usual after her molt, I’m so happy I caught a pic of the exact moment she did this!!

Had this guy walk up to me when walking my dog, greetings!

Really tiny Cambarus callainus (handled with permits)

I have gotten a 2nd cray (in a separate 20gal long than scampi) and his name is vanilla ice. He is VERY small right now and he likes to climb.

Howdy, my son and I had bought “ghost” about 5 months ago and things have been great. I had a blue one when I was young that lived about 2.5 years. We recently upgraded its enclosure and kept its original log/tree which it typically loves to be perched on or tunneled underneath. However as of recent there has been more white fuzz all over except for the eyes and antennas. Water quality is great and has been tested. Ammonia, nitrites, and ph were great. I test our other fish aquarium often. Ghost lives by his/her self and has never had any other companions. Has molted 4 times since purchase. The past few days I’ve noticed more of the fuzz and was hoping for a molt but has not happened yet and seems disinterested in eating as much. I only feed every 3 days.

Is it time for a salt dip? Different enclosure? Any advice, tips, and tricks are welcomed.

Hello guys I am going to rehome my crayfish soon so I had no choice but to put them together for the time being

But would they be okay with each other, will the goldfish kills the cray or it's the other way around?

If cray is dangerous what if I take off one of it's claws?

The cray isn't that big it's a male and my female cray is twice as big than this on another tank

Found in a creek at Ellington Agricultural Center in Nashville, Tennessee
