Got this fish for my 100-gallon tank. It’s quite active and aggressive, so I made sure to keep it with larger, calm fish. It’s a striking red sea color and adds a lot of visual interest. Needs a lot of space and a well-established environment. Not for beginners.

Placed it in a 75-gallon tank with some larger fish. It’s aggressive and has chased a few smaller species. I’m monitoring closely. The color is vibrant and it’s a unique addition to the tank. Would recommend only for experienced aquarists.

This trigger fish is a showstopper. The red color and movement are impressive. I’ve kept it for over six months and it’s still active. I ensure the tank has plenty of hiding spots and no corals. It’s definitely not for small tanks.
