| Yellow Tangs and many other marine fish have a
mutualistic relationship with some species of shrimp like the
skunk cleaner shrimp ( Lysmata amboinensis). The fish swim to the
shrimp and allow them to clean away and eat bacteria and other
micro-organisms that parasitize its scales. The fish minimizes the
chance of getting a disease or infection and the shrimp gets a meal.
The tang also has a commensal/mutualistic relationship with sea
turtles. When sea turtles come into the shallow reef waters from the
deep ocean, they have algae growing on their shells and tangs flock
to them eating the algae.
The Yellow Tang has become a popular fish in the
home aquarium because of its beauty and its feeding habits on algae.
It is a relatively peaceful fish if not mixed with fish of its own
genus. It may become territorial to the addition of new fish but
with gradually accept them.
The Yellow Tang can contract many diseases if the cleaner shrimp is
not around, however the most common is saltwater ich.Saltwater ich
is a protozoan that causes small white spots on the scales of the
fish. It also causes loss of appetite and in later stages lesions.
