Freshwater Fish

Nutrition

There are numerous types of food available for freshwater fish. Pellet and flake food can be used in most cases for freshwater fish. Some fish are carnivores and require live food such as goldfish, brine shrimp and even live tubifex worms. Frozen and freeze dried foods are becoming more popular and a very affordable option.

Care
Habitat

Freshwater fish typically are found in rivers and lakes. Some fish even venture into the ocean and become "brackish" which means that the fish thrives in environments where a small amount of salt is present.

Large fish produce more waste than small fish so more frequent water changes are required to maintain optimal water conditioners. Aquariums that are properly stocked will thrive with less often water changes.
