fish vs. crayfish?

Question

i hav a crayfish n im getting a fish w/ those big cheeks lik goldfish n can i put them together cuz i dont got nother tank?

Answer 1

NO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 2

no. there are very few fish that can live with crayfish. you need fast moving top dwellers like hatchet fish.

and when you say like goldfish do you mean the goldfish with the big eyes? because those have to be alone or only with other goldfish like them. also, you'd need a huge tank for the both of them, because crayfish should be in 20gallons, and the minimum would be 10gallons. goldfish need 20gallons. so you'd need preferably a 40gallon tank for them.

*edit*
after reading someone bellow me I would like to add that I was assuming you have the only kind of crayfish most pet stores sell with is a blue crayfish (not a lobster but they're sometimes called blue lobsters) which have a compatible temp for hatchet fish. however, even hatchet fish can become crayfish food, so no fish is a safe bet to put with a crayfish, hatchet fish are just the best choice if you want to put fish with them.

Answer 3

Definitely do not do that.
The gold fish with big cheeks assuming its the bubble eye you are talking about will be fish food for the crayfish, or if anything they will kill it for the sake of it.

I don't advise putting any fish with crayfish, even hatchet fish who dwell at the surface because the crayfish lives in a temperate environment and the Hachet fish is a tropical. Either too cold for the hachet fish (chilled, stress which will lead to death) or to hot for the Crayfish which will lead to faster matabolism and faster aging - death.

Answer 4

Generally, no. A crayfish will try to catch and eat the fish. Some fish like to rest on the bottom of the tank at night; if your fish is of this sort, then the crayfish will eventually kill the fish.

Answer 5

The crayfish will eat your fish [if it can get ahold of it].
I advise putting them in seperate tanks.

Answer 6

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

Crayfish

Basic Biology
Common Name: Crayfish (Crawfish, Crawdad, Freshwater Lobster, etc.). There are some 150 species in North America, over 540 species worldwide.

Color and size varies with species, diet, and age. Most are red, some are green, brown, tan, or blue with black or orange markings in various combinations. Often juveniles will be a light tan color that turns to a deep red as an adult. The coloration depends in part on their diet, and can change with a change in diet. Adult size is 2" to 6" for most US species. Some Australian varieties can be much larger.

They grow by molting, that is they shed their carapace (shell) when they outgrow it, and form a new hard shell. When they first molt they are soft, and very vulnerable to attack by other crayfish or fish. It can take a couple days for the new shell to fully harden. Juveniles can molt every week or so. Adults may only molt a couple times a year, and only under the right conditions. The empty shell should be left in the tank, where it will be consumed over the next few days to recover the lost minerals and help form the new shell.

Lifespan: about 2-3 years, but varies with species. Some live longer.



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.



How to get a crayfish
Here in California Crayfish can be purchased from some pet shops or bait shops, or you can catch them in the wild IF you purchase a fishing license or are under 18 years old. There is no season and no limit.

Answer 7

Sure you can,but first dark night you'll have one fat crayfish.

Answer 8

my crawfish,crawdads, ate all my fishes in my pond and they grew up to be nice size and then we ate the crawfish ! YUM

Answer 9

Fish they stink less.
