The Emerald Crab feeds on uneaten meaty foods and many types of nuisance algae. Unlike many other animals, Emerald Crabs will eat bubble algae and helps clean your aquarium of these algae. Its distinct, flat shiny green body and hairy legs easily identify the Emerald Crab.
Care needs to be taken to ensure an ample supply of food is available for the Emerald Crab. Many aquarists supplement the Emerald Crab’s diet with dried seaweed and chopped meaty foods, such as shrimp, as well as a quality pellet fish food.
Like other invertebrates, the Emerald Crab does not tolerate copper-based medications or fluctuating water parameters. Drip acclimation is recommended, as the Emerald Crab is intolerant of sudden water parameter changes.
