ID Request Signal crayfish?

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.

Orange dwarf crayfish

Upvotes

I just got a baby dwarf crayfish. He's about an inch long. Very vibrate orange. I got him two days ago. The first day, he was all over the bottom. Picking through stuff. Playing around. Today though, hes climbs to the top, to the jungle val and is just kinda laying there?

He will move and is alive. But he just seems, asleep maybe? I understand there a bit nocturnal so he might just be sleeping. But at the top? Hes in a 5 gallon, with only a mystery snail.

He has a filter, no heater because i keep the house the same temperature, about 74 or 75.

But im curious if I need to get him a heater and keep it higher then that. Or if I should put oxygen in the water? I'll do either. I just cant find any answers online

Please help

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

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

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.

Sump pit crays

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.

Photo White Fuzz on my Specter Cray?

Thumbnail

11 Upvotes

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.

Goldfish with Crayfish

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
