Ryan Sutherland –
The Acanthurus Tristis has been a great addition to our 80-gallon reef tank. It’s active and doesn’t damage corals. We’ve had it for three months and it’s thriving. The fish is semi-aggressive but doesn’t pose a threat to other tank inhabitants.

We added this fish to our tank after researching compatibility. It’s been calm most of the time and has started grazing on algae. We’re happy with the behavior and appearance. Needs a stable environment though.
