Common name: Flatworms
Scientific name: Platyhelminthes
Platyhelminthes, commonly known as flatworms, are a diverse group of simple, soft-bodied invertebrates. In reef aquariums, hobbyists often encounter two types: the beneficial microfauna, which are detritivores, and the parasitic flatworms, like the notorious 'red planaria' that can harm corals. Identification and management are key, as beneficial species contribute to a healthy ecosystem, while parasitic ones require prompt attention to prevent damage to the reef.
