Description
Planaria (platyhelminthes), also known as turbellaria or flatworms, are unwelcome guests in an aquarium, some of which can even pose a threat to nursling fish.
Owing to their nocturnal lifestyle, the presence of these pests quite often goes completely unnoticed.
These animals can multiply in huge numbers, which can ultimately result in an infestation.
In fresh water aquaria their victims include moulting shrimps, small shrimps and their offspring, but also weak animals, juvenile fish and eggs.
Flatworms can also live in marine water aquaria, however, large numbers of which can cause damage to corals and other animals.
