A clutch of mystery snail babies has begun hatching! Mom is a wild, or black, mystery snail. She started laying clutches about a month after I got her, and I remove them usually. I left this one clutch on the glass and lo and behold there's babies! Problem is, I have been removing pest snails as I see them, and now I can' t tell what I have in my tank! How can I discern between cuties & evil ones? Also, will my danios hurt them? Thanks for any help!
