Bluespot Butterfly Care Facts

Care Level: Moderate
Temperament: Peaceful
Diet: Omnivore
Reef Safe: No
Minimum Tank Size: 50 gallons
Max Size: 6 inches
The Bluespot Butterfly (Chaeodon plebeius) is a beautifully colored Butterflyfish, found among the Indo-Pacific ocean. They have a bright yellow body with a blue splotch towards the middle section; along with horizontal stripes and a black stripe acting as a false eye. They are very hardy and 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.
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.
