Clark's Clownfish
Clark's clownfish is one of the largest and hardiest anemonefish, a bold, active swimmer that ranges more widely from its host than most clowns. It is the least fussy about anemones, accepting nearly any of the ten host species, but it grows territorial and semi-aggressive with age, so it is best added last and paired rather than crowded with other clownfish. Colour is variable across its range — typically a dark body crossed by two or three white bars with bright yellow-orange fins and a pale tail.
