r/Crayfish

My daughter got her pet crayfish from her 2nd grade class after studying them from tiny babies; unfortunately, it died over the weekend after 18 months due to an unsuccessful molt.

She is distraught and I want to see if I can find a new baby crayfish for her to raise. 

She had a Louisiana Crayfish that was full of character and did the funniest of things as well as bare his claws at me e very time I walked past!

I want to get her a replacement and would like to get another Louisiana Crayfish as they are bigger and seem to be pretty hardy.

However I am open to suggestions for other species if they are relatively big (no dwarf species) and full of character. We would have to order via mail so that may limit options

I am open to suggestions and DMs if you don't want to post publicly.

Thanks in advance!

I am currently setting up a tank for a pair of CPO's. I have read about the necessity of having a lid, which totaly makes sense to me, but now i am wondering if i have to adjust the opening for cables. The aquarium (Fluval flex) also has a seperate compartment for its pump and filter where they could get into if they should decide to climb the back wall. How cautious do i really need to be here? Any shared experiences are welcome!
