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.

Golden apple snail vs river snail

River snail and apple snail are all gonochorism but is it possible to mate with each other?
River snail is male because his tentacle is different each other. One is straight and the other is a little round at the top of it. And apple snail is definitely female.When two golden snail is mating, the top is male and the other is female..
It is very difficult subject for us.
PLS, Let me know it is possible or not ~~
