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 ~~

When there is no enough food in aqua, crayfish attack "guppy".  A vicious cray attack a guppy using his powerful cheliped and sharp craw.
But fortunately my student rescued "guppy" from predator's sudden attack.

Neighbor or enemy ?

                                        Will guppy be a new neighbor or prey for crayfish ?

                                But the other vicious crayfish glare at guppy gloatingly to attack.
