Should I worry about bristle worms?
You might get squeamish at the sight of a worm squirming around in your tank, but it won’t bother you (or think twice about your presence). However, there is a small chance that a fireworm made its way into your tank. They are NOT dangerous to humans and won’t even bother your fish, corals, or crustaceans.
What happens when you touch a fireworm?
The bearded fireworm is a slow creature that is not considered a threat to humans unless it is touched by a careless swimmer. However, when the bristles are flared, they can penetrate human skin, injecting a potent neurotoxin, causing severe irritation and a painful burning sensation in the area where they are touched.
