Freshwater fish feeding

Freshwater fish are available in many types and sizes. Except for swimming in water there is usually less similarities than differences. Fish are broken down by means of breeding like egglaying fish or livebearers. Also the way they take up oxygene in their blood can be very different like the labyrinth fish and fish with normal gills. Also the way food is being digested can be very different. This asks for food that is individually tuned in to the type of fish you keep in your tank. Because people often keep a variety of fish in their tank they also need a variety of fish food or mixed feed.
