Freckled Hawkfish (Forster’s Hawkfish / Blackside Hawkfish)
The Freckled Hawkfish, also known as Forster’s Hawkfish or Blackside Hawkfish, undergoes color changes several times during its lifetime. As a juvenile, it is burgundy with a yellow tail. As an adult, it may be pink, brown, or an olive color. The black or red freckles on the face are constant throughout its lifetime.
A 70 gallon or larger aquarium is necessary for this fish. It hunts crustaceans and smaller fish, and it should be the last fish introduced to a semi-aggressive to aggressive community of fish. It becomes very territorial and will harass new additions including other hawkfish and fish that are much larger than itself.
The Freckled Hawkfish diet should include a variety of marine meats, frozen preparations, and live feeder shrimp.

The Freckled Hawkfish is a striking fish with beautiful color changes as it grows. We kept it in a 75-gallon tank and it has been active and healthy for over a year. It does get territorial, so we introduced it last and avoided adding other fish. Feeding it marine meat and frozen shrimp works well.

Great addition to a larger marine setup. The face freckles are very noticeable and the fish looks vibrant. We noticed the color shift from juvenile to adult stage. It’s active but only when feeding. We keep it alone to avoid conflicts.

It’s a beautiful fish, but very demanding. We had to keep it in a large tank and avoid introducing other fish. It was initially shy but became aggressive after a few weeks. Feeding it live shrimp helps with activity.
