Care
Care notes
Parameters: temperature 22-28°C, pH 8.1-8.4, salinity 1.023-1.025, dKH 7-12. It feeds on microalgae, detritus, and leftover fish food. A tank of at least 20 liters is sufficient for a small group. It is compatible with all peaceful fish and invertebrates. Avoid predators like pufferfish or aggressive crabs. It needs a sandy substrate and live rock for hiding. No special lighting is required, but moderate light promotes algae growth. It is sensitive to high nitrate (>20 ppm) and phosphate (>0.1 ppm) levels.
