Has anyone had them? I was curious how hard is it to keep them.

Thank you

i heard they are easy to keep, u just need a filter and then they wont die
(they may kill each other though)

i have two kind

white clakii - bought $3 each + shipping
they were 1-2 inch when i recieved
one month later - 4-5 inches already
attack and kill each other - got pretty shocked
they eat everything - food fish plant driftwood , sponges , even themselves
i think u should have bigger than 40g to keep 4~5 of them

CPO - they are as big as full grown rcs
but already got pregnant -_-
i think they cant even catch fries
i kept them only 3 weeks now though

I found CPOs to be fragile. I had a pair that didn't make it past a month. Might have just been my tank not being appropriate for them but just a heads up.

I also have marbles crays/marmorkreb. These are self-cloning and only need one to reproduce. I've found these to be virtually indestructible, except when I had a bunch that were being kept in a small tank and one got killed, most likely by each other. I have kept a pair in an unfiltered tank with water changes once every few months and they were still really active. Of course that's not the case anymore, they have a larger filtered tank and plenty of hiding spaces. These aren't good for planted tanks though; they will eat your plants, for me at least.

Most of these are territorial to some degree. I started this spring with 4 small crayfish from the stream behind my house (no idea what species.) I now have one large crayfish. It killed and ate the others for certain. That's just my species of course, but you hear much the same from people who keep them.
