also known as Lubbock's Fairy Wrasse. Though the male Tricolor Fairy

will best thrive in a well-established tank, with live rocks cleverly
arranged to provide hiding places, as the Tricolor Fairy Wrasse can

for jumping, so it is suggested to have a tightly fitting lid, or top on
your tank to prevent escape.
