We all love to keep our beloved pets in prime condition. Doing that involves getting a lot of things right, from their habitat and stimulants, to their co-residents and the attention we give them. But one of the factors which has the greatest impact on their health and general well-being, is their diet.

A good diet can be the difference between a healthy fish, full of vigor and vitality, and a poorly fish, with a weak immune system and who is prone to illness and injury. That is why choosing the best saltwater fish food is such a vital decision, and one that shouldn’t be made lightly.

When we look at all the potential fish food on the market these days, it is very easy to be bamboozled and not know what to look for. But there are just a handful of things that a good diet achieves.

For example, your chosen fish food should provide all the nutrients that saltwater fish need to survive and even thrive. This includes of course, all the hearty vitamins, minerals and fatty acids that are beneficial to their health.

Food is predominantly an energy source, so you should also ensure that the type and quantity of food you give is enough to meet their energetic requirements, which could vary with the season. The right balance of protein and carbohydrates is also critical.

This may seem like a lot of information, but rest assured, that is why we have assembled this handy guide to all the best saltwater fish food available on the market right now!

2. San Francisco Bay Freeze Dried Mysis Shrimp

[amazon box=”B000UZJSC6″]

Although complete foods like the one mentioned above are the most convenient and practical for the busy, modern fish owner, there is a strong argument to suggest that it is better to feed your fish a balanced diet of freeze-dried foods and other supplements.

For example, it offers them all the flavor and locked in natural goodness of live food, but without the risk of introducing unwanted infections or parasites to your fish tank.

3. Omega One Garlic Marine Pellets

[amazon box=”B007R52C2K”]

This is an excellent offering from one of the biggest names in the industry. Omega One is a large American company that prides itself on sourcing and processing only the highest quality ingredients to make the best saltwater fish food. The ingredients in this product are no exception.

One of the main advantages of this product, is that, as well as being a sinking pellet, the small 2 mm pellets are insoluble in water. This means the pellets are very unlikely to disintegrate in the water, causing detritus and the eventual influx of algae.

This food will give your fish all the basic energy and vitamins it needs, however it is not made with the same premium level ingredients as some of the other products.
