It is completely peaceful and compatible with most reef inhabitants.

Care
Care notes
A tank of at least 20 liters is sufficient for a small group. Water parameters should be stable: temperature 22-28°C, pH 8.1-8.4, salinity 1.023-1.025. A setup with live rock and a sandy substrate is ideal. It feeds mainly on algae but will also accept algae wafers and leftover food. Avoid copper-based medications as they are toxic to invertebrates. It is sensitive to large salinity swings.
