Reticulated Damselfish
Dascyllus reticulatusAlso known as Reticulate Dascyllus, Two-stripe Damselfish, Headband Humbug
Reticulated damselfish form tight social groups that hover just above branching coral colonies, plucking drifting plankton from warm lagoon currents. At the first sign of danger, an entire cluster retreats simultaneously into the dense limestone branches of Pocillopora or Acropora corals for shelter. Males maintain distinct territories among the coral heads, vigorously guarding demersal egg clutches by fanning water over them until they hatch.

- Approach Pace: Glide slowly toward coral heads to watch them feed without driving them into hiding.
