Easy to care for and very active in the tank. The orange color stands out well among other fish. I’ve had it for three months and it’s still healthy and showing good color. Perfect for a beginner reef setup.

It’s a vibrant addition to my 30-gallon tank. Not overly aggressive, but does defend its territory. I noticed it’s more active during the day and enjoys the coral structures.
