Maldive anemonefish's Behavior & Ecology
Amphiprion nigripes is active during the day. It is a protandrous hermaphrodite, which means all fish are hatched as males and later can change sex to female. The males live in harems in which an established dominance hierarchy manages the group and keeps individuals at a specific social rank. It also aggressively defends its territory and is completely dependent on its sea anemone which represents its "life insurance" as a safe shelter for the group and for the nest. The associative relationship that binds the clownfish and the sea anemone is called mutualism. The fish lives within the sea anemone's tentacles and can use it as a shelter because it has developed a thin layer of mucus which covers its body as a protection against the anemone's stinging tentacles, and the presence of the clownfish can be interpreted as a lure to attract potential anemone prey close to its tentacles; the clownfish can also defend the anemone against some reef fishes which could eat the tentacles, such as butterflyfish.
Maldive anemonefish's Feeding
This anemonefish is omnivorous and its diet is based on zooplankton, small benthic crustaceans, and algae.
Maldive anemonefish habitat
This species inhabits lagoons and reef slopes (Astakhov 2014). It forms a commensal relationship with sea anemones (i.e., Heteractis magnifica) (Fautin and Allen 1992, Kumar et al. 2011, Litsios et al. 2012). In captivity, fecundity has been measured at 16 events yr-1 (Siva and Haq 2017). Eggs have been measured at 2.0-2.2 mm in length and 1.0-1.2 mm in width (Kumar et al. 2012). The maximum total length is 11 cm (Fautin and Allen 1992).
This species is a minor component of the aquarium trade. Bleaching events have occurred in the Maldives; however, it is unknown as to what extent it is affecting this species populations and its host anemone populations (G.R. Allen pers. comm. 2010).
