Edward White –
The Acanthurus nigricans added a great visual presence to my 75-gallon reef tank. It’s active but not overly aggressive and blends well with other fish. I’ve had it for three months and it’s thriving.
David Jones –
This fish is a good fit for intermediate reef setups. It’s semi-aggressive and doesn’t cause issues with other tank mates. Growth is steady and it’s easy to spot in the tank.
Colin Peake –
I was cautious about adding a semi-aggressive fish, but this one has been peaceful in my tank. It’s active during the day and helps maintain the tank’s ecosystem.
