snails newbie

hey I know it is a water site but I'm a noob and I want to help me and others for snail care. btw if a snail pro wants to stick with me and guide me not only would you be super helpful but will talk to you personaly an share pics of raven. raven is my snails name.

I noticed a few snails in my aquarium and am curious if these are desirable or undesirable snails. I am currently working on cycling my first tank (so, newbie). It's a 55 gallon planted tank - - I've got a java fern, anubius nana, and pogostemon helferi that were 'tube plants' from PetSmart...
