Procambarus Alleni AKA blue crayfish?

[TattdxMama]

I've been thinking really, really hard on setting up a specimen tank for one of these guys. I wanted to ask a few questions before I take the plunge and invest in a specimen tank.
How hard do you feel the care is?
What size tank do you have/recommend?
Any tips, pointers, suggestions or things I should keep in mind?
I keep looking at different sites and keep seeing different recommendations and I'm a little confused. Thanks!!!

I've kept the natural form of this species and they are really hardy. They're not picky when it comes to food. Some tips I have are have a good lid. I once had crayfish escape and my mom thought it was a centipede and almost cut him to bits. Keep the water treated well as in use aged tap water and dechlorinater.
