How to Care for Porcelain Anemone Crab

written by Dave Burr

The Porcelain Crab usually lives together in pairs in an anemone which provides protection. It uses its large claws to fend off predators. Although they will compete with clowns for anemones, clownfish usually win the competition.

Growth: Maintaining proper Ca, Alk, & Mg levels is important for growth of their shells.

Care Level: Easy
Reef Compatible: Yes
Diet: Carnivore, filter feeder
Range: Indonesia
Family: Porcellanidae
Water Conditions: 75-80° F; sg 1.024-1.026 (1.025 is ideal); pH 8.1-8.4 Ca 420-440 ppm, Alk 8-9.5 dKH, Mg 1260-1350, Nitrates <10ppm, Phosphates < .10ppm

Water Chemistry: It is important that proper calcium (420-440 ppm), alkalinity (8-9.5 dkh - run it 7-8 if you are carbon dosing) , and magnesium levels (1260-1350 ppm) are maintained. Raising magnesium levels gradually up to 1400-1600 ppm can help to combat algae outbreaks, just keep CA and Alk in line as you raise the Mg. Nitrates should be below 10 ppm and phosphates should be below .10 ppm. We recommend doing a water change when Nitrate levels rise to 10 ppm. It is important to replace your phosphate media when phosphates rise to .10 ppm. Media Reactors make the most efficient use of your phosphate media by fluidizing it.
