Loaches or Cobitidae

At the bottom of rivers, lakes, and even some streams lives an amazing family of fish that often goes unnoticed due to its secretive nature. We are talking about loaches, also often called gobies. This is not one specific fish, but a whole group of small bottom dwellers united by their love of quiet, silted places.

Outwardly, they may seem unremarkable — usually elongated, resembling small eels or worms. But take a closer look, and you will discover their main feature: many species have several pairs of funny antennae around their mouths. These are not just decoration, but an important tool for finding food in murky water, as these fish often do not have very sharp eyesight.

Their lifestyle is closely connected with the bottom. Some species, like loaches, can burrow into soft mud, while others, like loaches, prefer to hide under rocks. This is their way of waiting out danger, heat, or cold. They are also real living barometers — sensing changes in atmospheric pressure, they begin to behave restlessly, for which they are popularly called “squeakers.”

For aquarium enthusiasts, some loaches, such as spotted loaches or acanthopthalmus, have become real favorites. Not only do they wriggle around on the bottom in an amusing way, but they also help keep the tank clean by eating leftover food. In nature, these modest fish play an important role as part of the food chain and as cleaners of water bodies.
