If you want your aquarium fish to live a long and happy life, be sure that you are feeding them a high-quality diet that is appropriate for their needs. A large canister of fish flakes is not the appropriate food for all fish. A proper diet with strengthen the immune system of your fish, stimulating growth and activity. The often overlooked step of choosing the right type of fish food is crucial to the health of your aquarium. There is a surprising variety of fish food choices available.
Dry fish food choices include pellets, granules, flakes, and wafers. Each is formulated for a particular diet; some are based on plant materials, while others contain mainly animal or fish products. Some are fortified with vitamins or minerals, or are formulated to develop brighter colors in your tropical fish. Choose your dry fish food based on the species of fish. While dry foods are easy to store and use, they may not be the best nutritional option. Remember that the first ingredient listed on the food packaging is the primary ingredient. Avoid fish foods containing cornmeal or other ingredients that are not a natural food source for your fish. Feeding your fish poor quality foods will increase the amount of waste in the tank, reducing the water quality.
Small fish may do fine on fish flakes, though larger tropical fish require a specialized diet, and it is nearly always a much healthier option. If your fish is a carnivore or omnivore, their food source should include meat. Frozen bloodworms, small red mosquito larvae, are a very nutritious option for these fish. They are sold frozen into small blocks that look like ice cubes, making it easy to feed them to your fish. Other popular frozen foods for fish include brine shrimp or krill. Larger fish also enjoy earthworms and other worm species, which can be found at your local aquarium supply store. Large predatory fish enjoy eating small feeder fish, which is a natural food source for this type of fish.
Although high in protein, these options do not provide a balanced diet, and should not be the only food source. Instead, they should be used in rotation, adding variety to your fish's diet. Like people, they will grow tired of eating the same foods every day. Live or frozen foods can also be used to supplement dried pellets or flakes.
Fish that are herbivores tend to enjoy nibbling throughout the day, rather than eating large meals at specified times. An aquarium with real plants provides a valuable food source. Herbivores also enjoy eating spinach leaves, zucchini, cucumber, or peas, placed directly in the aquarium. Let these vegetables float in the tank for an hour or two before removing them. Some dried foods, particularly algae wafers, are also good choices for herbivores.
When choosing the healthiest foods for your fish, make sure that your choice reflects your fish's nutritional requirements, and don't forget to provide variety. A diet of dry fish food may not be enough. A balanced diet, chosen in consideration of the type of fish in your aquarium, will ensure that your fish have a chance to thrive. Be sure that you can commit to the unique dietary needs of each fish species before selecting the fish for your new freshwater aquarium.
