WHat's the best way to keep crawfish alive?

The first one's I caught I changed the water twice a day (thinking I'd keep the ammonia levels down)  and most died with in a couple days.  Maybe to much of a ph shock (are they susceptible to ammonia and oh like fish)...maybe to much tempature change to frequently and quickly....

Well I've have a few more fatties and they had water when I drove up to the mountain and all over all weekend. When I got home and unloaded the car.... I realized they were still in there but 98% of the water had spilled out But they were all still healthy and mean as ever...

I then read on the internet not to put to much water over them and so I only added enought to cover them about 3/4's the way and they seem to be still doing fine at the end of this week. I'll drain and add about a cup of water fresh water each day now.

Should I keep any food out for now? since there is no filtration biological or mechanical of any kind at the moment? I know to keep them for more than a week or two I should probably set up a tank with some kind of filtration/ low airation.....

 Huh? Huh? Huh? Huh?

I would love to be able to keep some alive for extended periods of times and any advice is appreaciated

You are on the right track... dont cover them in water, enough water so 3/4 of them are covered or less.  You dont need to change water every day either twice a week should be good... you need to change it after feeding them.  Hotdogs, bologna, or something like that is what I fed ours.  If you have one die remove it as soon as you see it.  I also just used tap water they didnt seem to mind... if the lake you catch them out of is dirty you may have to change the water every day for the first couple days as they clean their systems out.

Okay taking out some water i just added...

Guess that would allow for them to keep it aerated well also..

I'll lower back to about where 3/4 of them are covered.

Keep it room temp, or in the fridge?

Okay done... I didn't really want to buy another air pump anyway when I know I have extras and can't find them.


Yours look great! How long could you keep them like that? Was overcrowding a problem?

Should I toss in a tiny piece of leftover kfc chicken wing? It's been a rough rime for them and they been in there close to a week so far...

Only kept mine about 3 weeks before they ended up as bait... but the site I read the guy said he keeps his year round in the garage at room temp... Im sure they will probably eat the wing I used hotdogs and it was very messy.

Interesting about how he kept them in the garage because that where they were for the last 3 days with virtually no water from after the trip.

Right now they are in my room cause my a/c unit will keep it below 72 but they might just end up back in the garage after I transfer a bunch of oil that's been building up from oil changes and I need to make some room.

Thanks for all the advice Rick.

Okay right now I still have the 4 fattys from a week ago that made it. Gave them 4 pieces of dog food and they ate most of it... saw a bit left over.... pulled the craws out dumped the water....put the craws back in... at this point a bigger craw grabed the smallest of the 4 and held him upside down by his belly. I they added water back to about where it was (covering 3/4th) of them) and they seem to be doing fine.

Hey Rick, Did you ever notice a limit to where over crowding them caused them more injury from fighting and less of a time they would live? By the picture you showed.... it doesn't seem like it... Grin

Right now... I just has the 4 craws in a 5 gallon bucket.... seems I could fit 3 more without them starting to stackup.....

Guess that's why you used a developing tray or whatever....

I only had 2 die and I assumed it was from not getting any of the food or something like that.  Maybe if I would of kept them for a lot longer I might of had issues with to many but the guy I got the info from had a setup where he had them stacked on a 3 tier shelf and just drained the water from one to another always adding new water at the top 3 times a week and said his trays were pretty full.  Id say once you start losing some there are to many, lol.

Here's a link I found on a persons experience


http://www.anapsid.org/crayfish.html



"Captive Care

Water conditions
Not critical. Freshwater, but can tolerate a wide range of conditions. Cool, hard, alkaline, well aerated water is best for most species.

A temperature range of 65-77 F (18-25 C) is best for good growth of most species from the continental United States, but they can survive over a much wider range. Some species are tropical, some require cold water.

If the water is too soft or the pH is too low then there is a risk of calcium deficiency that could inhibit molting. Medium hard or hard water with a slightly alkaline pH, 7.5 - 8.5, is best.

They are normally 100% aquatic, but they can survive out of the water as long as their gills remain wet. They do not need to leave the water. The tank should be covered to prevent them from climbing out and going exploring around the house. They can climb up between the tank wall and a under-gravel lift tube, or climb up plants or a heater.

Diet
Omnivorous-fish, shrimp, meat, vegetables (frozen peas, boiled zucchini, carrots, etc.), sinking pellets, table scraps. Don't feed too much fat. Adults do not need a lot of protein, and should be fed primarily vegetables. I feed mostly frozen peas, some Tetra Tabimin pellets, carrots, and they catch the occasional fish. They also like the crickets that drown in my toad tank (the toads won't eat dead crickets).

Since they like vegetables they will eat many plants. They will devour plants that nothing else will eat, like Java Moss. They will uproot the plants they don't eat. I have lots of floating Hornwort (Ceratophyllum demersum) in my tank. They don't eat that too fast (it grows fast), and they like the cover above them.

Behavior
Nocturnal. They like to hide during the day and need hiding places. Pieces of PVC pipe, rocks, driftwood, etc., can be used. They are cannibalistic if they are crowded or not provided with suitable shelter and lots of food. They can pinch HARD, so be careful.

Compatibility with fish
Crayfish will try very hard to eat your fish. They will lay in wait until a fish swims through their open claws, or if they have their tail curled up they can lunge forward a few inches to try to catch a fish. They may climb up plants to go fishing near the surface. I've seen them watch food that is put into the tank from a few inches away, and wait for fish to start eating it. Then they lunge forward to try to catch one.

I now have a single crayfish in a 10 gallon tank with White Cloud Minnows, feeder guppies, and a Chinese Algae Eater. The crayfish ate some of the guppies but the survivors are keeping out of reach. She ate all of my Zebra Danios, and half of my White Clouds. The Chinese Algae Eater is much too fast for her, and it even hides with the crayfish and sucks on her back. I'd recommend feeder guppies, feeder goldfish, or minnows from a bait store (anything cheap).

In the past I kept a crayfish with common (feeder) goldfish, and the crayfish was not able to successfully compete for food against the goldfish. I had to "hand" feed it with a pair of tongs. One day I came home and the four goldfish (about 3" each without the tail) had eaten about half of the 4" crayfish, and they had it well cleaned up by the next morning. I've also seen small goldfish get caught and eaten within a few minutes. Do not keep a crayfish with a fancy goldfish or any fish that is slow moving or has long fins. Do not keep them with Weather Loaches (Dojos), as they will lay on the bottom of the tank and allow the crayfish to walk up and pinch them."

Thanks Rick... With that many in the picture and only 2 dying.... I'd say that would be pretty normal and guess it was nothing you did. Looks like you had a successful setup for sure...

Good name for Mean Albert!  He looks like he's ready to tear you a new one if he could only just get a hold of you.   Cheesy

Yeah he earned it... He'd grab the other ones there torso and hold them up side down.... (some the same size) He always had his clays up when I was grabbing one so he ended up being last....

Reminds me...I tossed him a piece of dog food...should go change the water in a bit...
