ottos need atleast 10 gallons, and snails need more because of their heavy bioload. You can have no other tank mates in that small of a "tank".
You are better off just scrubbing it off, and not having to do more water changes.
Plecos can grow up to 2 feet, and need atleast 100 gallons for a fully grown one.
