mikrovorm

Mikrovorm refers to a small, worm-like organism often encountered in aquariums, particularly in planted tanks and freshwater setups. These organisms belong to the genus *Nematoda*, commonly known as roundworms, and are typically microscopic in size, measuring between 0.1 and 3 millimeters in length. They play a crucial role in the natural decomposition process by breaking down organic matter, such as uneaten food, fish waste, and decaying plant material.

Mikrovorms are often introduced into aquariums unintentionally through substrates, live plants, or contaminated equipment. While they are generally harmless to fish and other aquatic life, their presence can indicate an imbalance in the tank’s ecosystem, such as excess organic waste or insufficient filtration. Some hobbyists intentionally introduce them to help maintain a healthy biological filter by accelerating the breakdown of detritus.

Distinguishing mikrovorms from other microscopic organisms, such as copepods or rotifers, can be challenging without magnification. They lack the segmented bodies of annelids (bristle worms) and the more complex structures of larger worms like tubifex. Their slender, cylindrical shape and smooth cuticle are key identifying features.

In well-maintained aquariums, mikrovorms are usually controlled by natural predators, such as shrimp, snails, and certain fish species. Overpopulation may lead to cloudy water or an unpleasant odor, prompting a need for increased maintenance, such as water changes or substrate vacuuming. While not a primary concern for most aquarists, monitoring their levels helps ensure a stable and healthy aquatic environment.
