nas snails

[nipit8]

why do these snails climb to the top of my tank when the lights are out??--Is that normal?

 

[marcah]

perfectly normal they only come out at night and when food is put in ( but not always) other then that they sift through the sand all day..​

Some time even bury them self into the sand

I also found sometimes it might be a sign, test things again
