Buyer's Handbook

There are literally hundreds of types of saltwater fish that are kept in home aquariums, and they all have somewhat different dietary needs. However, it is recommended to provide as much variation in the fish’s diet as possible by providing new items on a regular basis.

Fish, like any other pet, need a diet that’s rich in nutrients if you want them to live long, healthy lives. There are fish species that will only eat food that floats, while there are others that will only eat food that sinks. Remember this when searching for fish food.

Foodstuffs for fish of various varieties

There are as many distinct kinds of fish food as there are fish species. Different types of fish, such as carnivorous, omnivorous, and herbivorous fish, have varying dietary needs. The following are the most frequent shapes and sizes of fish food.

  • Flakes. These are the most widely accessible and well accepted variety, and they are perfect for little fish. In most cases, they’ll float for quite some time before making their way to the tank’s floor. The biggest problem is that these flakes readily break up into finer particles, which might cloud the water in your aquarium.
  • Granules. Granulated food often sinks slowly, so it’s accessible to all of the fish in the tank. They are often in bite-sized slices, making them appropriate for little and medium-sized fish. If they aren’t entirely consumed, these granules can make a mess and even block your water filter.
  • Fish pellets sink gradually and come in a variety of sizes to accommodate fish of varying sizes. This is not always the case, though, as they can potentially create blocked filters if not entirely devoured by your fish.
  • In a freeze-drying process and then frozen. Feeding freeze-dried bloodworms and mealworms to carnivorous fish is a common practice. Carnivorous fish, of course, benefit much from live worms as well.
