Hey guys! So, a while back, ( a couple months or so) i got about 30lbs of eco-complete from some guy for 15 bucks. it had been sitting in my closet for about a month, maybe a little longer, waiting for me to get my tank set up so i could start cycling it. Im doing a fishless cycle, as i was about to start dosing the ammonia, i noticed a little spiral shelled snail on the glass. Im a little confused as to how it survived in my closet, ( when he gave me the substrate it was slightly moist) then i noticed two more, one was big, as I type this theyre currently burrowing into my substrate, which means theres probably alot more. Just scanning the surface of my substrate i see about ten sticking out. I have no idea what kind of snail they are, if they are the pest kind, or what i should do with them as im going to start cycling my tank today. Ive included some pictures. Thanks for all your help!
