The fish looks beautiful with its powder blue body and gold rim pattern. It’s active and doesn’t seem to harm the coral. I’ve had it for three months and it’s thriving in a 75-gallon tank. Easy to care for once the water parameters are stable.

The coloration is striking and matches the description well. It’s semi-aggressive but doesn’t attack other fish. I noticed it’s more active during the day and settles down at night. Good for a reef setup with proper tank size.

I bought this tiny Acanthurus leucosternon for my new reef tank. It’s been adjusting well and has not shown any signs of aggression. The gold rim pattern is very visible and adds a nice touch to the tank.
