Reborn crayfish

2 crayfishes had survived about 6 months in my small aqua.
After death of them, only 2 tortoise have occupied their shelter without fight.
But, my new curiosity was arised again.
2 new crafishes live together with them recently.
One of my students promised that he will take care of them well.
His name is Sijune who want to be "zoologist" in future.
