Well, your persistence paid off, those are nice pix!

The problem with breeding, is that you have to have two in the same tank w/o them killing e/o. in order to do THAT, you need a fairly large tank, with plenty of cover/places to hide.

However, having accomplished that, I find crays very easy to breed. At the lab, once the female is in berry (has a bunch of eggs underneath her abdomen... aka "the tail part") we separate her and put her in a large plastic bin with about 4" of water and holes punched in the lid. Once the babies hatch and detach from mom, you can put her back into her original tank... there to start the process over again.

If you just want more crays, I say go to your local stream and catch more, because it's probably a lot less time consuming!!:D catching crays is as easy as finding a shady bank, a slow moving stream, and either... a) a willingness to get pinched or b) a bucket and some chicken liver. (place chicken liver in bucket, place/sink bucket right side up in stream... crays crawl in to get liver, you pick up the whole bucket). Traps are even easier, but buckets are cheaper!




I want to issue a warning for people who have Cherax species( Quads, etc...) about putting other species of crayfish into the same tank..
Depending on where you live and what crayfish are native you could have a huge issue.
cherax are not immune to the crayfish plague and NA crayfish are carriers. If you combine the two and you have a carrier NA cray your Redclaw will be dead within 10 days....

I have to disagree with the growth statement.
They can grow much larger than 6 inches.
And if it is the Walkamin Strain it will grow twice as fast as the regular Redclaw...
I have Redclaw or Cherax Quads that are 15 inches in length(nose to tail)....
They are over 2 years old but they are large none the less.....

Thanks for the info, I have mine for just over a year and its 6 inches long now.
Been feeding her a lot of calcium rich pellets and everything else she likes, also once in a while she grabs a guppie that are breeding in her tank and enjoys some meat :naughty:

Hope it doesn't grow too large, otherwise will have to get her a new tank hehe
 
NIce pics..
 
I love these, i have a 20 gallon tank with 6 tiger barbs and a red fin shark, would a blue crayfish fit in well?

Crays eat fish, I have mine with a lot of guppies, just breed them there and once in a while a few go missing, so I wouldn't recommend it.
 
We have two blue crays about 6" long...Jake and Elwood. They take just about anything that falls into the tank but...as you can see from my rather poor attempt to take Elwoods picture...niether are very photogenic. Each of them set up residance in hollow log ornaments on either side of the tank and only come out to fill their carefully stocked pantrys. They even moved the rocks around to form a ramp and Elwood uses one of them as a door.

he is a nice vibrant blue...good job
 
i've got electric blue crayfish like yours and i have some bigger light blue crayfish in my big tank. I don't feed them anything specifically, i bought them to be tank janitors. they eat what the fish don't.

the fish eat bloodworms, raw tuna, raw market shrimp, frozen krill, bloodworms, brine shrimp, turkey and chicken hearts and hunks o beef heart. i also put 4 or 5 algae disks in each of the tanks every other night for the plecos and snails.
