Diet Details
In the wild, Spot-Nape Butterflyfish feed on small crustaceans and zooplankton. In captivity, they require frequent small meals of live or fresh foods such as mysis shrimp, enriched brine shrimp, or copepods. Many refuse dried or standard frozen preparations and require acclimation to captive diets.
