The Black Triggerfish is a striking addition to my 120-gallon tank. It’s active and curious, and it enjoys the meaty foods I offer. I had to rearrange some rocks, but it’s a fun and visually interesting fish.

It’s a beautiful fish with a unique appearance. I feed it squid and clams regularly. It’s not shy and will explore the tank, though it does move rocks around occasionally.

After a few months, it’s grown to about 3 inches and is very active. The diet has to be varied and includes shrimp and krill. It’s a great centerpiece for a reef tank.
