Yesterday she looked like she had a couple less eggs than the day before but now I come home and she only has around 4 eggs!?!?!? I know they couldn't have hatched because she has only had them for 3-5 days. WHERE DID THE EGGS GO???????

It suddenly not moving anymore, the tale fin is under the crayfish, and the eyes are full black, it looks lifeless and when I grab it, it is floppy. Is it dead or not?

Hello I have a blue crayfish and I was just wondering if it is normal for my crayfish to skip some meals.

Then i just had another question about my tank systems, all I have right now is a filter for the tank, is there anything else that I need or should get for my tank and crawfish?

Madison county Kentucky

I have a lot of brine shrimp eggs that I used to feed my goldfish with and also hatch for fun sometimes. btw I’m a very new crayfish owner, I got my first ever crayfish a couple days ago and I don’t have any experience with that.

found an uninvited guest in my cray's tank. i recently added some driftwood + rocks but they were all boiled for a significant amount of time so i don't know where it came from: regardless, i did not put it in the tank and don't know what kind of snail it is. could it potentially harm my cray? should i remove it or let it stay until it inevitably meets it demise at the claws of my bloodthirsty beast?

Hello everyone, can someone help on identifying the sex of this crayfish? Thanks.

I've found my female berried! I hang out in r/shrimptank but I'm not well experienced in what to expect with these guys as far as babies. It's it close enough to keeping shrimp that I just let her do her thing? Do I need to separate? I don't want her stressed.

I'm so excited to have babies! TIA for any advice

I’ve got two juvenile marbled crayfish in a tank together and I’ve only seen one molt in the past 2 months, is there something I’m missing that’s causing them to grow slowly?

•the tanks footprint is ≈4sq ft, with 8 hides

•I’ve got an oversized filter, and I do a 50% water change 1-2 time per week

•I feed them an algae wafer once per day, with occasional blood worms or pieces of fruit. There’s always leftover food so I don’t think I’m under feeding.

•there’s crushed oyster shells at the bottom of the tank for calcium.

•I have one air stone for the tank

•I keep the tank is covered for ≈23 hours a day, it’s supposed to be a breeder tank so I don’t look at it often

i've recently noticed an odd shape/discoloration on the side of my crayfish.

i added some new rocks and driftwood to his tank 2 days ago or so, which i did collect myself but i treated them thoroughly by boiling all added items for 30 minutes each, as well as tested the rocks with steel and checked with vinegar for a reaction; all seemed safe. i know the rock in the picture has some black spots, but considering i boiled the rock for a suitable amount of time, i don't believe it should be anything dangerous.

my main concern is just the odd shape. i've considered shell rot as a possibility but it doesn't seem to match with the images i find online for shell rot, so i'm not sure. water parameters such as PH, nitrites, nitrates, and ammonia are all fine. i don't have a way to check the hardness or alkalinity, but i don't expect there were any drastic changes in those properties considering the rocks were free of reaction when i tested them.

my cray's tank was rather barren before adding the new stuff, only had the dark logs you can see in the first image, and he's become far more active as he's got a lot more to explore. he seems much more lively and there isn't a single spot in the tank where i haven't found him at least once. but i'm concerned i might have missed something when sterilizing the wood and logs and somehow gotten him sick.

if it helps to diagnose, he's also a girl. he's laid eggs before. i've just always called him 'he' since before i was even aware, so it's just stuck. he hasn't molted in a month and a half or so, but prior to that he molted twice within a two week period. i'm not aware of how many molts he had before that or exactly how old he is.

if anybody has any insight, i would really appreciate any words of advice or info.

He never eats. Everytime I give him food he puts it on his head and bows down. Can anyone help?

Hi, I have two adult self cloning crayfish, and this morning before work I noticed little itty bitty babies hiding in the nooks and crannies especially near my sponge filter, so it's official: they have cloned. I saw maybe 5 or so but I bet there are more.

1. How did they escape my notice? As far as I know I didn't see either crayfish in a berried state. How long does it take the clones to incubate and detach from the firstborn? Are they visible to the naked eye immediately at the point of detachment or have these "children" been wandering about the water column as tiny tiny almost invisible larvae for a while and just now got big enough?

2. The other inhabitants in the tank are only a school of 8 fathead minnows, which are at full adult size, about 3.5 inches each. These all coexist in a heavily planted 75 gallon tank.

3. What are the best, natural methods of population control? What fishes would feed on the babies but maybe have trouble eating the full grown adults? I like the idea of a completely self sustained food web/chain in my aquarium, so ideally the fish and snails would eat detritus/bits of food, the crayfish would eat the snails and pick at my copious amounts of Java moss and guppy grass that I plan to continuously sacrifice to them from my other tanks, and then what would eat the crayfish? That's where I'm at rn. I want to figure something out before too many of the offspring grow to adulthood. I don't mind having a total of like 3 or 4 adults who can escape predation and keep cloning but I don't want this tank to become overrun. I might ask this in the aquarium subs too. Thanks in advance!

i’ve got my cray in a 10 gallon right now i’m gonna switch out her filter as it’s getting old and not running as good as it used to, any good filter recommendations for a 10 gal as well as anything i should pair the filter with?

I have this 20 gal that’s very spacious, is planted, will add more rocks and hiding places. Considering in adding one but for a 20 gallon only one cray seems overkill, so for having them long term, how many can i have in a single tank or which tank mates can they have, that they at least dont kill
