The vase worm, also called vase lumbrics or Tubifex, is a type of annelid vein that lives in the muddy funds of rivers and ponds. They are often used as living food for aquarium fish and are also commonly used in aquarophilia to help maintain water from the clean and healthy aquarium by feeding on organic waste.
The vase worm is a relatively small animal, generally measuring between 1 and 2.5 cm long. They have a grayish or brown color and are covered with small hairs which allow them to move in the mud. They also have small eyes and many segments ringed along their body, each with suction cups which allow them to fix themselves firmly at the bottom of the water.
The vase worm is mainly herbivorous and feeds on plant debris and bacteria present in the bottom of the water. However, they can also feed small animals such as insect larvae if they find them.
Vase worms are often used as living food for aquarium fish, as they are considered a healthy and natural source of food for fish. However, it is important to buy them from reliable suppliers because they can sometimes be contaminated by bacteria and dangerous parasites for fish.
In addition to their use as food for fish, vase worms are also used in aquarophilia to help maintain water from the clean and healthy aquarium. They feed on organic waste present in the aquarium, which can help reduce the levels of nitrates and phosphates in water and prevent the growth of unwanted algae.
It is important to note that vase worms are not suitable for all types of aquariums and should only be used in biotope aquariums or muddy background aquariums. They are not suitable for community style aquariums and can cause problems in these types of aquariums if they are used incorrectly.
In summary, the vase worm is a type of annelide verge which lives in the muddy funds of rivers and ponds. They are often used as a living food for aquarium fish and can also be used in aquarophilia to help maintain water from the aquarium clean and healthy by feeding on organic waste. However, they are not suitable for all types of aquariums and should be used with caution to avoid any problem.
