One thing I'd like to add about Marissa's and their babies,is that they have HUGE appetite's and will eat almost anything including live plants,and other snail clutches & live babies.
I have a huge Rubbermaid tub that houses Cana's,Brig's,Spixi's,and Marissa's.
I was always adding babies from other tanks because there was alot of room & also want to mention that because this tub's water is so good,that alot of eggs have been laid by all the different snails.By chance,I noticed that all the babies were disappearing-all newborns/all bigger babies,etc.and found out on Applesnail why---The Marissa's!!

Anyway,that's one way to keep your population in check.
