Electric Blue Crayfish

Hi I was at the LFS today and noticed that they had an Electric Blue Crayfish in stock. This really caught my eye, and having just received a 55 gallon, I have room for it. I have a couple of questions on crayfish in general.

A- What do they eat?
B- Will they harm my fish?
C- Are they hardy?
D- Would you recommend them for a community tank?

Thanks for any help, and since the crayfish is 20 dollars, my decision to purchase the crayfish is based solely upon the posts you leave.

A
-
Crayfish are opportunistic omnivores. Crayfish will eat anything, meat, fish, plants, flake food, pellets, fish poop, other crayfish, they will try to eat anything! They are scavangers and hunters

B
-probably will but if you get fast top swimming fish it may not catch them. marble crayfish have a better reputation with other fish than most crayfish, but thats not a
Guarantee he wont eat it. They will eat dead fish.

C
-yes, they can survive many different water parameters

D
-No, The only crayfish you MIGHT be able to use that I can think of that are more safe for community tank are marbled crayfish or Dwarf crayfish.

10 gallon tank - 2 Ghost shrimp, fry, 1 Soft shell turtle, 5 crayfish, 1 baby catfish
10 gallon tank - 1 marbled crayfish in berry
50 gallon tank - 2 male guppies, 1 female guppy, 2 zebra danios, 1 pearl danio, 1 Angelfish, 1 male platy, 2 female platys, 2 silvery minnows
Pond - 1 cooter, 1 RES, 4 goldfish(my baby sis poisoned my pond)

I heard that the rule is 10 gallons per crayfish but a worker at the LFS told me that I could easily fit one or two into a 5.5 gallon with no problems, what do you think? They aren't too big.

Is it ok to mix an electric blue crayfish with a plain brown one?

How long should you cycle a tank before adding a crayfish?

One 29 Gallon - Lots of Fish
One 10 Gallon - One White Crayfish
One 15 Gallon - Baby Bullfrogs

I can give you an educated answer to this, but can you post a list of what you currently have in your tank community? Thanks

Sure. As I already said it is a 55 gallon. There are: 2 dojo loaches, 12 zebra danios, around 5 cories, and some small pink rainbows. This is what I have in there currently but soon I think I will be mixing it up and getting some new fish and kicking out the danios.

Pretty sure the crayfish might mess with the dojos or cories

One 29 Gallon - Lots of Fish
One 10 Gallon - One White Crayfish
