Different diets for different species
Feeding freshwater fish a sensible diet that is suited to their species is absolutely crucial. Proper feeding supports a healthy immune system, promotes growth and breeding, improves the appearance of fish and encourages activity. Different species of fish require different diets so it is crucial that you research the eating habits of the fish you intend to have in your tropical freshwater aquariums.
Discovering the right consistency and type of food
The type of diet and food consistency can be judged by considering three divisions of two groups.
The first category is the type of food. Herbivores eat plant-based food only, omnivores eat both plants and animals, and carnivores are meat-eating fish. Most fish fall into this third division.
There are also different levels at which fish feed in aquariums so it is important to present food in a texture suitable for fish which collect food from the top, fish that feed on food which has fallen into the water, and fish that gather food from the bottom of aquariums.
What's on the menu?
All fish require a balanced diet rich in proteins, fats, carbohydrates, vitamins and minerals. Here are a variety of foods you may consider, depending on the nutritional requirements of the fish in your fish tanks.
Herbivore fish need food high in fibre, for instance algae and vegetables. These fish will enjoy spinach, lettuce, nettles, zucchini, carrots, peas and maize. You need to make sure that these vegetables are boiled so they are soft, and broken down into reasonably sized pieces. These foods contain lots of vitamins, minerals and trace elements. I also recommend using Spirulina for herbivores as it provides them with easily edible vegetable protein.
For carnivores and omnivores, a diet rich in protein will be essential. This can be supplied through live food (ensuring it is healthy), home-grown or commercial foods. Thin slices of cooked white meat or raw red meat can be used, live small fish (e.g. feeder goldfish), freeze-dried or live worms, daphnia, brine shrimp, Tubifex, and krill. Meat, brine shrimp and worms are best fed as a delicacy rather than as an everyday food. Tubifex encourages growth and may be used as a conditioning food to get your fish in good condition before reproduction. In my opinion, I suggest krill as a dietary mainstay for carnivorous and omnivorous fish. They are rich in protein and contain amino acids and Omega 3 fatty acids for general health, carotenoids to bring out bright colors in fish, vitamins and minerals which boost the immune system, dietary roughage for better digestion, and energizing carbohydrates. Krill are also low in salt and fat. They are ideal for enabling a sick fish recuperate or to bring an already healthy fish up to optimum fitness for breeding or showing. For predatory carnivores who like to catch moving things, you can dangle non-live food from a fork and lower it into the fish tank in front of the fish, wiggling it around so that it seems it is alive!
Dry foods
There are various types of dry foods such as granules, pills, flakes, grains, pellets and wafers. All of these can be bought in a choice of textures considering the type of fish you would like to feed and the various depths of the water column they live in. The majority of these prepared foods are of a high-quality, intended to supply a balanced diet and are fortified with extra vitamins and minerals, so it is essential to add them in the diet. Different formulas can also be used at times such as preparation for breeding or for developing color. It is also very practical being easy to store and doesn't require any preparation. The risk of disease or parasites being brought into aquariums with food is also completely removed.
Bon Appetit!
Variety is the real key to high-quality fish nutrition. Therefore, it is essential to give your fish a variety of different appropriate foods to guarantee they are given a balanced diet for their optimum health and their interest in and enjoyment of food.
