Bursa Trigger (Rhinecanthus verrucosus) – Sea Dwelling
The Bursa Trigger is an easy-to-keep fish that is not reef safe. It requires a 125-gallon aquarium or larger when fully grown. The tank should include ample rock for hiding and plenty of open space for swimming.
Feed this fish meaty foods such as squid, krill, clams, small fish, and hard-shelled shrimp to support the constant growth of its teeth. While most triggers show some level of aggression, they thrive when kept with other active, competitive fish that can share feeding time.
This species will consume clams, ornamental crustaceans, small fish, and snails in a reef environment. Maximum adult size is approximately 9 inches. Shipping size ranges from 1 to 2.5 inches.

Got my Bursa Trigger and it’s been thriving in a 150-gallon tank. The fish is active and eats regularly on squid and krill. It’s not shy and enjoys the rock structure for hiding. I keep it with other active fish, and they all seem to get along during feeding times.

The fish arrived healthy and grew well in our tank. We provide meaty foods daily and it’s always hungry. A bit aggressive at first, but after a few weeks it settled with the other fish. Needs a large tank, but worth it for the look and behavior.

Easy to care for once the tank is set up. The fish is curious and swims around a lot. We feed it clams and shrimp, and it’s very active. Not reef safe, but perfect for a large freshwater or saltwater setup with space and hiding spots.
