I have a nerite snail in a small 10g community tank that keeps going on adventures at night. I have found him various places on the stand and in the floor. He has a small amount of damage on his shell so I'm guessing that my cat got curious on one of his outings. Anyway, he's getting out next to the HOB filter and I'm not sure how to prevent it. Could this be a food issue? There isn't much algae in this tank, if any so I was wondering if that could be a cause for wandering snails. Also, I am considering putting him in my 60g Malawi tank. There is plenty of algae in there on the rocks but I'm fearful that the labs will bother him. Any advice or thoughts are appreciated. Thanks in advance.
