Bumble Bee Snail
The Bumble Bee Snail is a small, strikingly black-and-yellow-banded predatory snail, not a peaceful algae grazer like the rest of this list — it hunts small worms (including bristle worms) and vermetid snails at night, which makes it genuinely useful for pest control but also a real risk to other cleanup-crew members and small ornamental worms. Reef and hobby guides consistently rate it "reef safe with caution" rather than fully reef safe, and recommend starting with just 2–3 individuals and observing their impact before adding more.
