You cannot sell native crayfish legally!

I think you will also find that keeping more than one cray per tank(unless you have a big tank) they will fight all the time and are carniverous.


Hey count yourself lucky you've got one.
Im having enough trouble finding one

Correct.
It is easy to see how fast they will go through that. Take a tank of green water and add one mussel. I guarantee that within a few hours the tank will start to look clearer. Within a day it will be almost clean.
No matter what we do we cannot supply the quantity of food they require.

No matter what the petstores try to tell you, they are not captive bred. All Kakahi sold in the pet trade ( or any trade for that matter) are wild specimens removed from their natural environment.

I've got some H polysperma 'sunset' and a little bit of R rotundifolia but I've recently been treating for IPs so I'd recommend a sterilization dip first - if you're okay to do that you're more than welcome to a couple of small bits.
