How to Feed a Betta Frozen Food

A tropical fish must never be fed frozen or very cold food because its digestive system will go into shock, so always defrost frozen fish food thoroughly before feeding your fish. Bettas, also known as Siamese fighting fish, are carnivores and relish live food, especially bloodworm. Frozen bloodworm is a nutritious alternative to fresh live food and is packaged in blister packs of 1/4-inch cubes. These are far too big for one fish, so you need to cut it down to make it into a suitable-sized serving for your betta.

Instructions

    • 1

      Fill one of the tubs a quarter full of water from your aquarium and put it to one side.

    • 2

      Punch the frozen bloodworm cube out of its blister pack and place it on a spoon. Put the rest of the pack back in the freezer right away so it does not begin to defrost.

    • 3

      Crush the cube carefully between the two spoons so it starts to break down and pieces begin to fall away. Pick up some of the bits that break off and drop them into the tub of aquarium water. These take 10 minutes to defrost completely and will turn the water very slightly red.

      Scrape the remaining frozen bloodworm into the empty container while you wait for the other tub to defrost the worms. The frozen worms now have less structure than the original cube and will be easier to separate next time you want to feed your betta frozen food. Replace the lid on the container with the remaining frozen bloodworm and put the tub in the freezer.

    • 5

      Pour the water and defrosted bloodworm mixture into your aquarium. Your betta will quickly find the worms as the residual blood in the water acts as a scent marker, attracting the fish to its food. You won't be able to see the red coloring once the water is put back into your the aquarium as it disperses completely.
