Lom & Nigrelli, 1970

Brooklynella hostilis is a parasite of marine fish, found in wild fish, farmed fish and aquariums.[1] It is kidney-bean shaped, and approximately 60–80 μm long,[1] with bands of cilia.[2] B. hostilis is the only species in the monotypic taxon Brooklynella, a genus in the order Hartmannulidae.[3] It reproduces by binary fission.[4]

B. hostilis causes the disease Brooklynellosis, also known as slime-blotch or clownfish disease.[4] In marine aquariums, B. hostilis infects most teleosts (ray finned fishes).[3] B. hostilis feeds on dead skin cells and can cause severe damage to gills.[5] Affected fish have a gray discoloration, and may breathe abnormally fast or abnormally slow.[2] The infection can cause sloughing of skin, and congestion of the gills.[6] The parasite spreads rapidly, and can easily transfer to a new host.[7] Formalin is an effective treatment.[2]
