Okay you guys the only tank I have live plants in is my 29 gallon and I don't have any snails in there. The only other tank I have is my ten gallon and at first I had some plants in ther but I moved them in about a week to my 29 so I don't think they came from there. Then I got new gravel and put it all in my 10 and removed the old. This is when I started to see these tiny snail shells. I just started removing them because they had no snails in the shells but the other day one was clinging to the side and it had the snail in it. This is the only one I know of at the moment. I don't really mind him either I am just curious from where he came? Is it the gravel? Because that's the only thing that's in this tank that's not in the 29 gallon. Also I put some plastic plants in there that have been in my closet for almost 5 months now. And then where in my 29 gallon too so I don't think that's where they came from. Thank in advance. ;D
