Crayfish issues

[Dirty Old Man]

I have a 10 setup for crawdads that I use as feeders. I started the tank with roughly 30 of them (most less than an inch long.) That was maybe a month ago. I haven't used even half of them (I'm feeding a green spotted puffer) and I'm down to 3. One of them is pushing 4". The other two are maybe 2" Any ideas on why they keep disappearing? The water level is only @ roughly 6" (about 4-5" from the top) so I know they're not crawlin' out.
If they're eating/killing eachother, is there any way I can stop/slow it down?

I am stupified. Are there any remains in the tank at all?

95% of the time, no. Out of those that I had, I pulled out maybe 10 shells, over half of which were from them molting.

Do you have a cat scooping them out on you or something? Any air tubes that they are crawling up?

You're pulling out empty shell because the crays are cannibalizing the soft-bodied tankmates. If left alone, crays will eat their molts. Young fast growing crays are highly cannibalistic on any smaller slower growing individuals. Cannibalism can be lowered slightly with frequent feedings but not stopped since they cannibalize for mineral replenishment as well as for food.

gotcha. That would make sense. Any ideas on how to breed them?
