Emerald Crab
The Emerald Crab will make a valuable addition to any aquarium because they will take care of bubble algae problems and clean up the rockwork. They are reef safe and very easy to take care of, which makes them ideal for beginners. They are very hardy and can withstand harsh conditions, like large temperature changes or parameters out of their optimal range. The Emerald crab typically stays hidden during the day in small crevices in the rocks and then comes out at night to feed. Their diet consists largely of organic debris but should still be supplemented. Provide a meaty diet a couple of times a week to help this crab thrive.
