Hello.
 
Around 6 months ago I stumbled upon a new fish shop with loads of exciting stock.  I couldn't resist and purchased a tiny 'Hammers Cobalt Blue Lobster' (Cherax quadricarinatus - The only legal crayfish allowed in UK).  I had plenty of space in my 30+gallon for more fish and thought I would make the purchase.  When I got him he was just over an inch long and vivid blue.  After moulting almost once every 3 weeks he has grown into a massive 8" crayfish!!! He has eaten/destroyed all of the living plants in the tank which I expected but he has left all of the shrimp and fish alone.  He has destroyed the pond and MTS snail populations but cannot eat my nerites.
 
Anyway here are a few piccies of him and also a link to a video of him eating and the fish trying to steal his food

This is him when I first got him, only 1 claw from being in a small tank!

Here is the link to a video of him in the community tank! The fish and shrimp bother him more than he does them!

Well there’s mixed results (I have done a lot of research) I think bottom feeding fish are out but most other fish seem okay. Main thing is to keep him on a diet of veg as if he gets the taste of fish too much he may become more aggressive!  I am amazed at the personality he has so I guess like fish they can vary with temperament!
 
I have Dwarf Rainbowfish, Neons, Celestial Pearl Danios, Red Cherry Shrimp, Amano Shrimp and Nerite Snails in the tank, all of which are still here after 6 months.  All he has eaten in the MTS snails and Pond Snails, guess because they are so small with weak shells!

Hi Olivia.  He's a sweet little crayfish. Looks like a 'Procambarus clarkii Orange' but I may be wrong
