Care notes
A minimum tank size of 40 L is sufficient for one specimen, but larger (100 L+) provides better stability. Parameters: temperature 24-28°C, pH 8.1-8.4, salinity 1.023-1.025. A rocky setup with grazing surfaces is ideal. Diet: natural microalgae, supplement with dried seaweed if needed. Compatible with all peaceful fish and invertebrates. Beware of predators like crabs or angelfish. Avoid copper-based treatments.
