Interesting Facts

  • They are fast swimmers and will often dart to the bottom and bury themselves in the sand whenever they are approached.
  • Fishermen consider them nuisances because they are very good at stealing bait off a hook
  • They are cleaner fish, cleaning parasites off of other fish. Once they start cleaning, other fish gather to be cleaned as well. But once they are full, they swim away, leaving the uncleaned fish to fend for themselves.
