Keeping Snapshot:
DOWNLOAD THIS CARE SHEET Preferred Water Parameters:
  • Temperature: 22-27 degrees celsius
  • pH Level: 7.5-8.2
  • General Hardness: Moderate-Hard

Range: Occurs in tidal zone of shorelines across Northern Australia.

Reproduction: Can not be successfully bred in captivity.

Feeding: Omnivorous, eats most fish foods. Commercial foods also available specifically for crabs.

Additional Comments: Amphibious rather than fully aquatic,provide a partially filled aquarium, landscaped to provide plenty of habitat for the crabs above water. Expert escape artists, so use a tight-fitting cover. Fish tankmates must be large enough to not be eaten by the crabs, but not too big where the fish might start to consider the Crabs as a potential food item! Scarlet Fiddlers prefer slightly brackish water rather than freshwater.
