But there isn't room here
for two predators

The grouper, braving the lionfish's
poisonous spines, tries to evict its rival

But lionfish are persistent

This grouper spent many hours simply
defending his hunting patch

Some animals prefer to avoid
conflict whenever possible

These harlequin shrimp,
having captured a starfish,

are taking it back to a safe house
beyond the reach of competitors and danger

The problem with starfish is that
they have minds of their own

and five large sticky arms

By the time the shrimps have prised
off arm another has reattached itself

Only by manoeuvring the
starfish onto its back

can they have any hope of
gaining the advantage

Even so, getting it back home
is a major undertaking

The starfish is now a living larder

lf the shrimps can hang onto it,
it will feed them for days to come

The top of the reef is usually covered
by a thin layer of green algae,

another living larder

And many fish depend on it

Powder blue tangs defend their right
to graze on a particular patch

But for a larder as well-stocked as this,
there is always competition

When a shoal of convict tangs decide
to graze, little can stop them

The powder blue tangs
try to keep them off

But they are overwhelmed
by sheer numbers

The territory is stripped
of algae in minutes

The blue tangs appear to
be fighting a losing battle

But eventually they begin
to get the upper hand

They persist with their attacks until
the marauders are well on their way

When night falls,
some very strange creatures

creep out of crevices
and crawl over the reef

This moving bush is an animal
- a basket star
