Copperband Butterflyfish Diet | What do Copperbands eat?

Feeding is a critical part of achieving the successful care of a Copperbanded Butterflyfish. Known in the hobby as one of the most tricky fish to feed and maintain a healthy and balanced diet it’s no wonder people ask the question ‘ What makes a good Copperband Butterflyfish diet?‘ constantly if fish forums and in our Facebook group.

Why diet is so important when housing Copperband Butterflyfish in a home saltwater aquarium or Reef Tank.

  • Your fish will grow. A Copperbanded butterflyfish can be emaciated when first acquired, especially if it has had to endure multiple transfers, so it is important to set it on the right growth trajectory quickly by establishing regular feeds.
  • Staves off disease.  Larger fish are better able to withstand parasites and other infections that may be introduced to your tank if they are larger and better nourished.
  • Curbs predation of other reef dwellers. Though Copperbanded Butterflyfish are reef safe, as omnivores, they are known to nip the invertebrates that they share the tank with. This can be reduced by ensuring that there is a good supply of forage available and regularly offering live and frozen foods.
  • Helps keep your community of fish peaceful. A well-fed Copperband is a happy Copperband and minimizing stress will promote more settled behaviors.

Correct Copperband Butterflyfish Diet

Getting it right is not as easy as it seems, and it is well worth investing the effort in establishing your Copperband Butterflyfish on as many foods as possible. These butterflyfish are omnivorous and should have a range of live, frozen and flaked foods offered to maintain a good appetite.

Foods for a Copperbanded Butterflyfish include live foods such as:

  • Bloodworms
  • Glassworms
  • Black worms
  • Mysis Shrimp
  • Brine Shrimp
  • Aiptasia (which is helpful to limit its spread in your tank, though this should not become the majority of the Copperband’s diet)
  • Clams
  • Mussels
  • Insect larvae

It is helpful to start feeding your Copperband with live foods before transitioning them to frozen foods such as:

  • Frozen clams
  • White worms
  • Frozen shrimp

Rocks can be filled with these foods and then frozen to give the butterflyfish something to forage with its long nose.

In addition, a Copperbanded Butterflyfish with a good appetite may also eat flaked foods and seaweeds such as Japanese Nori, though these should only comprise part of their diet.
