Can I keep a Clown Triggerfish with other fish?

Clown Triggerfish are highly aggressive and often attack tankmates, so mixed-species tanks require caution. Many keepers house them alone or only with similarly large, robust fish.

Can it live in a reef tank with shrimp?

Its strong jaws let it prey on shrimp, snails, and other invertebrates, so keeping them together is not recommended. Adding one to a reef tank also needs careful consideration.

How large a tank does it need?

Adults reach 25 to 40 cm, so it's best to plan for a large tank even while the fish is still young. The exact size needed also depends on whether it's kept with tankmates.

Is this a good fish for beginners?

This species is generally considered suitable for experienced aquarists rather than beginners. It's worth building experience with saltwater fishkeeping before taking one on.

What should I feed a Clown Triggerfish?

It's a carnivore that naturally preys on hard-shelled animals like crustaceans and mollusks. Once acclimated, it will often accept prepared pellets and frozen foods as a regular diet.

Clown Triggerfish

The Clown Triggerfish is one of the most striking large-bodied members of the triggerfish family, instantly recognizable by its bold white polka-dot pattern and vivid yellow mouth. Also simply called the clown trigger, it has long been a favorite among saltwater aquarists looking for a bold, characterful centerpiece fish. That said, it is notoriously aggressive and often attacks tankmates, so it is generally recommended only for experienced keepers with a spacious, carefully planned setup. Reaching 25 to 40 cm as an adult and living 10 to 20 years, it calls for serious long-term commitment.

About Clown Triggerfish

Clown Triggerfish: a large, boldly patterned saltwater fish known for its aggressive temperament. Learn about its 10-20 year lifespan, 25-40cm adult size, and what experienced keepers should know first.

7 things to know before welcoming a Clown Triggerfish

1Highly Aggressive Nature
Clown Triggerfish are among the most aggressive members of their family and will often chase or attack tankmates. Many keepers house them alone, or only with similarly large, robust fish that can hold their own.
2Plan for a Large Tank
As an adult, this species reaches 25 to 40 cm in length. Even when purchased small, plan ahead for a tank large enough to give a full-grown fish room to swim.
3Suited to Experienced Keepers
This species is generally considered suitable for experienced aquarists only. A solid background in saltwater water-quality management and stocking compatibility will help before bringing one home.
4Requires a Long-Term Plan
With a lifespan of 10 to 20 years, this is a long-term commitment. Think ahead about future tank space and ongoing maintenance before deciding to keep one.
5Sturdy Layout and a Secure Lid
Strong and inquisitive, Clown Triggerfish can rearrange live rock and dislodge equipment in the tank. A secure lid is also recommended to help prevent jumping incidents.
6Avoid Crustaceans and Mollusks
With powerful jaws and teeth, this species preys on shrimp, crabs, snails, and other shelled invertebrates. Avoid keeping it alongside these animals.
7Temperament Changes With Age
Juveniles can seem relatively calm, but temperament tends to become more aggressive with age. Don't judge long-term tankmate compatibility based on a young fish's initial behavior.
