The Acanthurus Tristis has been a great addition to our 80-gallon reef tank. It’s active and colorful, and it doesn’t harm the corals. We’ve had it for three months and it’s thriving.

It’s a bit more active than expected, but we’re happy with the color and movement. Needs a larger tank, but it’s a good fit for a 75-gallon setup.
William Ferguson –
We added this tang to our reef tank after researching compatible species. It’s peaceful with other fish and doesn’t damage the live rock or corals.
