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 areopportunistic omnivores. Crayfishwill 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.
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?

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.
I can see the Crayfish possibly going after the Dojo's if it's not kept fed, BUT, I don't forsee the crayfish particularly being able to catch any of them, even if it tried. Now depending on the size of the CF vs. the size of the Cory's, I doubt he'll mess with them (although the Cory's are a slight bit slower than the Loach)...still, I don't see a problem with the Cory's and the CF. Just keep him fed. You think you're gonna pick him up?
I'm really not sure right now. Maybe in a couple of months bout right now I am slowly stocking the 55 gallon. As I said earlier the danios are going to be leaving, giving me more room to put in fish. I am also working on a convict cichlid tank because I have never been able to breed egg layers, and have heard that they are a good place to start.
I am not totally sure right now but danios can get a little boring. (dull) Speaking of crayfish, today I was at a lake and someone caught one and gave it to me. I put it in a 2 gallon. That someone happens to be on fish forum. I love MY new crayfish.
I want to share my blue crayfish story. Ive had him in this 48 gallon vertical tank for almost 2 years. Hes pretty cool, although he hides during the day mostly. I added him to a nicely planted tank, and he chopped up every plant he could get his pincher on (when I got him, he only had a left pincher. the right was totally missing. it has sense mostly grown back). He has only killed a couple of small guppies and one goldfish. but i always get tons of compliments, and when he comes out to eat and explore, he is the life of the tank.
that being said, I wont get another one once he is gone. lol
here he is attacking (unsuccessfully) one of my snails
here are the plants before he chopped them all up:
here is is, first time in the tank (note he only has one claw)
