Urban birds: ducks, pigeons, and sparrows are sedentary synanthropes. Searching for natural food will not allow them to survive the winter on their own. They either search for waste in landfills or feed in public places.

Aquarium fish feed in different layers of water. Their oral apparatus can be located low (they feed at the bottom), along the Central axis of the skull (they feed in the water column), and on top (they get food from the water surface). Therefore, depending on the species, each fish needs its own food. According to the nature of food, fish are divided into herbivores, carnivores, fry eaters and omnivores.
The feed must contain proteins, fats, carbohydrates, as well as minerals and vitamins. Under optimal conditions (which is not always the case), mineral salts can be contained in sufficient quantities in water and soil. All other components of fish are obtained with food (animal or vegetable origin). Continue reading
