Paul Oliver –
Easy to care for and very peaceful in the tank. It doesn’t bother other fish or corals. Perfect for a small reef setup. Grew to about 3.5 inches and stayed healthy for over a year.
Gordon White –
Loved having this fish in my 24-gallon tank. It’s calm and doesn’t chase other fish. Just needs a balanced diet and regular water changes.
Fiona Cornish –
Great addition to a beginner reef. It’s active but not aggressive. Has adapted well to the tank environment and shows no signs of stress.
