The good Dr. Ron says:
Numerous other fishes live in close proximity to sea anemones throughout the world's oceans, but until recently it was thought the Indo-Pacific host anemones harbored the only true "anemonefish" mutualism, where the fish was immune to the host's stinging capabilities. Recent work has shown that in the cool waters of the NE Pacific, there is another true anemonefish (Elliott, 1992). This fish is Oxylebius pictus, the convict fish or painted greenling, of the Pacific Coast of North America. The host anemones in this case are found in the genus Urticina . The fish is mostly found with the strawberry anemone, Urticina lofotensis, but occasionally with other species such as the fish-eating anemone, Urticina piscivora, as well. These anemones lack zooxanthellae altogether and are often predatory on fish, and they possess quite virulent stings. The sting of Urticina piscivora is sufficiently potent to cause long-lasting necrotic lesions on humans.
This association is facultative, as the fish may be found in areas lacking the anemones unlike the Indo-Pacific clownfish, which require a host anemone. If the anemones and fish are present together, however, most of the anemones harbor one or two fish. Larval Oxylebius pictus will metamorphose out of the plankton as juvenile fish directly on the oral disk of the anemone. The strawberry anemones are relatively small, generally no more than about 6 inches (15 cm) across the tentacle span, and the juvenile fishes are less than an inch long (2.5 cm) at metamorphosis. During their life on the oral disk of the anemone, the fish appear to feed on small ectoparasitic or commensal copepods that live on the anemone. If threatened, the fish may swim down through the anemone's mouth into its gut. The major predators on the small fish may be nocturnal octopuses and crustaceans as well as other fishes.
BTW I did a google search and came up with 183 pages of info. Try it.
And once again that informatin is good IF I correctly identified it.
