Hi all sifu(s),

As per title, i would like to start another tank with Tiger shrimps cantonensis caridina probably mix with Neo. I have a few question

1) I did some searching online and i can't seem to find info on how to sex them? Both sexes are the same color tone and it's so difficult to see saddle on the female, assuming those were female i saw in lfs. Some of the male the lfs guy shown me has curvy belly.

2) Does breeding occur by any chance if male is larger than the female?

3) This probably is not about shrimp but my Posorabbit snail, the shell looks empty in my other tank, does adult cory eat poso rabbit snail?

Please help.
