How to Feed Emerald Crabs

Emerald crabs (Mithrax Sculptus) make lively additions to a marine aquarium. Their vivid, ornate bodies contrast to the more subdued appearance of other cleaner crabs. Like many crabs, this species is a scavenger, which finds much of its food occurring naturally in the tank. Emerald crabs also help to keep algae under control. In a large, established tank, an emerald crab might be able to sustain itself, but supplemental feeding is advisable to ensure the animal gets enough to eat.

Instructions

    • 1

      Switch on the tank light for at least 12 hours a day. This supports the growth of the algae that emerald crabs eat.

    • 2

      Provide the crab with sinking, algae-based fish pellets or dried seaweed two or three times a week. Judge how much to feed by how quickly the crab eats. If it consumes all the pellets rapidly, feed more. If any are left, feed fewer next time.

    • 3

      Provide small pieces of meaty food such as shrimp once a week.
