Rabbitfish Care Guide: Reef-Safe Algae Eaters for Serious Hobbyists
Introduction to Rabbitfish Care Rabbitfish belong to the genus Siganus, a group of herbivorous saltwater fish from the Indo-Pacific region known for...
On the reef, Cirrhilabrus lineatus feeds on zooplankton picked from the water column above the slope. In captivity, that translates to a varied rotation of small meaty items: frozen mysis, enriched brine shrimp, copepods, Cyclops, and finely chopped krill or other marine seafood. Well-formulated marine flakes and small pellets work as supplements once the fish is settled and feeding confidently alongside tankmates.
Because a planktivore processes many small meals rather than one large one, offer food at least twice daily, and ideally two to three times per day. Newly introduced specimens benefit from even more frequent feeding while they build condition. This species can be sensitive during shipping and acclimation, so choose an active individual that is already eating, and inspect the mouth for transport injuries before purchase.

Expect an active, diurnal swimmer that spends the day cruising open water and darting back to rockwork when alarmed. Toward unrelated community fish it is peaceful and docile, though it can turn territorial toward other fairy wrasses, particularly rival males. Overly assertive tankmates are a poor match; intimidation often triggers frantic upward escape attempts and jumping. Keep one male per aquarium, or house a single male with a female or a small group of females where space genuinely allows. Females and subordinate individuals may shift into dominant male coloration and status over time.
For reef displays, this wrasse is a dependable choice. It leaves corals alone and coexists with ornamental invertebrates such as clams, snails, hermit crabs, and cleaner shrimp. The one caveat follows directly from its natural diet: very small planktonic crustaceans drifting in the water column may be eaten, so reef safety here should not be read as total immunity for microscopic or exceptionally tiny crustacean life. Introduce similar wrasses cautiously and with plenty of visual breaks in the rockwork.

FAQ
Frequently Asked Questions
About the Fairy Lineatus Wrasse
-
How large an aquarium does a Fairy Lineatus Wrasse need, and does it require a lid?
Plan on a 70-gallon aquarium or larger for an adult, with additional volume when other wrasses are present. A tightly fitted lid and secured overflow are essential because this species jumps when startled. -
Can more than one Lineatus Fairy Wrasse be kept together?
Do not house multiple males in a typical aquarium. A single male alone, or one male with a female or several females in a sufficiently large system, is the workable approach. -
What should this wrasse be fed and how often?
Offer small zooplankton-type and meaty foods such as mysis, enriched brine shrimp, copepods, Cyclops, and finely chopped krill, with marine flakes or small pellets as supplements. Feed at least twice daily, and two to three times daily for newly introduced fish.
