there are some apple snails at work that have the yellow shell and same shape etc as an apple snail but their body is a dark grey to blackish in some cases. what is going on here?

also how can i tell the difference between male and female apple snails?

thanks robyn youre a champ :) thanks to all your help my little teeny tiny apple snails are now the size of peas and doing great. could never have got this far without your knowledge

thank you

I would guess the differently colored apple snails are just color variants or maybe another species. Sexing apple snails can be done. I suggest visiting http://www.applesnail.net because they have photos and details on sexing and everything pertaining to apple snails.

The pea snails must be cute!
