Care Level: Expert
Temperament: Peaceful
Diet: Omnivore
Reef Safe: No
Minimum Tank Size: 120 gallons
Max Size: 12 inches
The Lined Butterflyfish, Chaetodon lineolatus, has a pearl white body accented with a thick black band over the eyes and very thin vertical black lines and yellow fins and tail. They are peaceful and can be kept with other peaceful fish, but may become aggressive towards other Butterflies with a similar pattern or coloration in smaller tanks. Since they are more sensitive than most other Butterflies, they are recommended for experts only.

They are also not reef safe since they will nip at and eat soft corals and stony polyps as well as ornamental shrimp, tube worms and anemones. Diet should include a variety of mysis and vitamin enriched brine shrimp, spirulina, nori, seaweed, marine algae, and algae based foods, 2-3 times daily.

Reef Safety for the Lined Butterfly


While the Lined Butterfly generally coexists peacefully with coral reefs in the wild, caution is advised when considering its compatibility with a reef aquarium.
