I bought this fish for my 75-gallon reef tank. It’s active and colorful, and it hasn’t damaged any of the corals yet. I keep a close eye on it, and it seems to be adjusting well. The beginner-friendly care level made it easy to start with.

The fish is vibrant and adds a nice touch to the tank. I noticed it occasionally brushes against soft corals, so I’ve rearranged the layout to give it more space. Still, it’s manageable and a great addition to a beginner’s setup.

After a few months, it’s grown quite large and is now a focal point in the tank. I appreciate the clear care instructions and the fact that it’s suitable for a beginner. No major issues so far.
