The snail is not really that interesting, just one of those things.
If it is a Malaysian Livebearing Snail, it could have arrived so small it would seem to be a tiny speck, and then burrowed into the substrate out of sight. If it is a pond or ramshorn snail, which lay eggs, it could have arrived as a tiny egg cluster or as a tiny snail and remained unseen for weeks.
If it is any of the above small snails, they are considered by most of us as helpful. They get into places we can't to clean, eating everything organic, breaking it down so the bacteria can better handle it. They do eat algae, though minimally, but still enough to help.
