About this fish
About this fish
Undulated Trigger is a marine triggerfish sold as Balistapus undulatus for the home saltwater aquarium. In practice, this species is typically kept in a fish-only setup where its bold, intelligent behavior can be enjoyed without risking rapid losses to curious invertebrates. Its strong jaws and assertive personality make it a good choice for aquarists with robust tankmates and a tank that supports active swimming and natural grazing on live rock.
Features:
- Bold and intelligent fish with a strong personality, known for active, engaged behavior
- Best suited to fish-only aquariums with live rock and robust tankmates
- Powerful jaws—plan feeding and handling around a fish that can be quick and persistent
- Often aggressive toward tankmates and may eat invertebrates, so choose companions carefully
- Diet centers on meaty foods; examples include krill, squid, and clam on the shell
- Help it settle after arrival by acclimating slowly and providing a quiet spot in the tank
