Who is this curious fellow?

A Spine-cheeked anemonefish
B Barber’s anemonefish
C Pacific anemonefish

Fact: At about 6.5 inches, the spine-cheeked anemonefish is the largest clownfish species. Like all anemonefish, it forms a symbiotic mutualistic relationship with sea anemones and is not affected by their stinging tentacles. The female is larger than the male, and pairs typically spawn and guard eggs near their host anemone.
