What is the best marine fish food?
Take advantage of all the different types of marine fish food that are available in the ocean.
Fish food vary from phytoplankton to zooplankton, macroalgae to mobile invertebrates, coral polyps and even other fish. Some saltwater fish are omnivores and are easy to feed in our aquariums, while others are specialists which struggle to feed on items that are different to the natural food they would find in the wild.
When we keep a mix of different tropical fish in our aquariums it’s important that each fish receives the right food type for it. It needs the correct particle size and the right nutritional profile, be it herbivore, carnivore, planktivore or corallivore. Feed your saltwater fish properly and they will be hardier, less shy and more disease resistant. Offer the wrong foods or in too little a quantity and they will sadly waste away.
The first foods to entice wild-caught saltwater fish are frozen foods. Artemia (also known as brine shrimp,) and mysis shrimp are small invertebrates that will tempt many marine fish from Clownfish and Damsels to Tangs, Angelfish, Wrasses and Gobies.
There can be a few issues though in that the nutritional profile of Artemia is actually quite low, meaning that although fish readily eat it, it’s hard to put weight and growth on the fish. And if you buy your frozen food online it arrives thawed out.
The saving grace, however, is to buy foods like Artemia, Mysis and Krill in liquid form. These don’t need to be stored in the freezer like frozen food, and also deliver whole crustaceans along with a soup of other particles which will guarantee to get your fish (and your corals,) feeding. So the new generation of liquid marine fish foods is well worth investing in, both for fish and corals.
Try dry foods for aquarium fish weight gain and nutrition
Next is to try to get your saltwater fish onto dry foods. Although made from raw ingredients like algae, fish and shellfish, a good brand of marine food can be made even better at the manufacturing level by making sure that all the key vitamins and minerals are present throughout the food. This makes many marine fish food recipes a complete diet for marine fish. Get your fish onto flakes or better still soft pellets and they’ll have fat bellies and they’ll be looking as good as they did on the reef in no time.
Frequency of feeding for marine fish
The other thing to know about most planktivores like Anthias and Green Chromis, and herbivores like Powder Blue tangs is that they need to feed really often, with six feeds per day not considered excessive. To do that load pellets into an automatic fish feeder, which release small amounts of food into the fish tank many times throughout the day.
And for the herbivorous fish, you can’t beat a stick-on grazer ring or an algae rich paste which can be smeared over rocks, enabling grazers to dine throughout the day and pick at the rocks for food, just like they would in the wild. So liquid foods, and better still, a quality brand of dry food, are the best foods for saltwater aquarium fish.
