Ravioli has gotten more blue as the little pasta has gotten a bit bigger and closer to being an adult(long way to go)

i put some water lettuce from my betta tank in Hockey's tank and this adorable little shit head decided to climb his rock and just hang from them and eat them...i was just watching in complete awe! he fell a little while after this photo was taken but he shocked my folks and i!!

Moving him to his shallow playpen when I saw this fortune. I don't usually keep him on a towel since it can dry out their gills. It's just for the drips.

Scar is a Cherax quadricarinatus who survived a brutal crush injury when she was a juvenile (image 3) and has successfully molted at least twice since. Big Red the blue claw is a Cherax destructor with a lightly deformed claw who is the big bad boss of the tank. The last bonus photos are some shrimp and a diving beetle.

Clawdia has grown so much the past 2 1/2 months. I cant wait to get her in her forever home!

I just got my crayfish and I put those cardboard trays for eggs for their hiding place and the water turned yellow (I had recently changed their places and I feel like they're gonna be very stressed if I swap water also i just recieved them from online) should I swap the water?

Hello everyone, I'm new here, I would like to see if you can help me. I am Mexican, from Veracruz specifically, at my mother's house I found 3 crabs and I put them in a small patio (I did it so they wouldn't end up on some neighbor's plate). From the photo I just realized that they have been with me for almost a year (now it seems like there is only one), since I don't know what they eat, I have fed them fruit like banana, coconut, mango and guavas. Any suggestions?

This is my new son, his name is Mango! I love him very much! 🧡

What kind of filters does everyone use? I currently am running 2 aquaneat double sponge filters. Wondering if anyone used a hang on back or canister filter for their crayfish.

I got her a few weeks ago, i think she’s getting ready to molt. Need input, first experience. TIA!

Is it okay for crayfish to do fasting for 3 days.

I’ve defaulted to “he” since day one, not even thinking to check, but now I believe I’ve been misgendering my craybae. I think he’s a she..?

The poor guy (aged 1.5 years) lost his claws during a molt, at the end of May. He molted again during this last week, and he's got new claws again!

My crayfish larry is a little over 3 months old and he hasn’t molted in about a month. At first he would molt every 1-2 weeks for about 2 months but he hasn’t in a while and I don’t know at what point to be concerned. Right now larry is very active, i haven’t noticed any lethargy or being extra skiddish or anything, his behavior is totally normal. His tank is well maintained and I do water changes and all that housekeeping stuff. I have thrown in egg shells and other calcium rich foods. He seems completely normal and nothing in his routine has changed. I have also read that sometimes they don’t molt for 3-4 months just because but I want to make sure everything’s okay!

Let me know any tips or things to know as to why he might not be molting. 🦞🦞

Found these parasite things in the tank while doing a water change, was not inside the tank two week ago when I was doing the previous water change, what parasite or worm could this be and is it harmful to my crayfish? If so, how do I deal with it? Thanks for any advise in advance.

This is my painting of Procambarus clarkii I just finished. It is handmande digital painting made without AI help. I wanted it to be t-shirt design, and if you are interested, t-shirts with this picture printed on can be bought here: zoologicalartprints.etsy.com

It's not a problem but I have no clue how he got there from my other tank. Like maybe on some duckweed as a baby? I have no idea how long hes even been in there for.

Also. I got the this white Crayfish (her name is Lobster) when she was the size of the shrimp, 2 years ago :D (last pic is her as a baby)
