Ecology. Known to live in association with sea anemones E. diaphana , Actinoporus elegans Duchassaing, 1850 , Bartholomea annulata , C. gigantea , Lebrunia neglecta Duchassaing & Michelotti, 1860 (as Lebrunia danae (Duchassaing & Michelotti, 1860)) , Laviactis lucida , and S. helianthus ( Silbiger & Childress 2008; De Grave & Anker 2017; Brooker et al. 2019). It has occasionally been recorded from the anemone-like corallimorpharians Rhodactis osculifera (Le Sueur, 1817) ( Williams & Williams 1982; Ritson-Williams & Paul 2007; both as Rhodactis sanctithomae (Duchassaing & Michelotti, 1860)) and Ricordea florida (see Wicksten 1995a), a scyphozoan jellyfish C. xamachana (cf. Criales 1984; Silbiger & Childress 2008) and a scleractinian coral Montastraea cavernosa (Linnaeus, 1767) ( González-Muñoz et al. 2019) . The species is well-known as a fish cleaner ( Titus et al. 2017; Horká et al. 2018).

Distribution. Widely distributed in the tropical and subtropical western Atlantic; 0–24 m depth ( Poupin 2018).
