When it comes to helping each other out, it turns out that some fish are
better at it than previously thought.

New research from the ARC Centre of Excellence for Coral Reef Studies at
James Cook University has found that pairs of rabbitfishes will cooperate and
support each other while feeding.

While such behaviour has been documented for highly social birds and
mammals, it has previously been believed to be impossible for fishes.

"We found that rabbitfish pairs coordinate their vigilance activity
quite strictly, thereby providing safety for their foraging partner," says
Dr Simon Brandl from the ARC Centre of Excellence for Coral Reef Studies.

"In other words, one partner stays 'on guard' while the other feeds --
these fishes literally watch each others' back," Dr Brandl says.

"This behaviour is so far unique among fishes and appears to be based
on reciprocal cooperation between pair members."

Reciprocal cooperation, which requires an investment in a partner, which is
later reciprocated, is assumed to require complex cognitive and social skills.
Skills that fishes have been deemed not to have.

Yet, Dr Brandl says their research shows clear coordination and presents
intriguing evidence for reciprocal cooperation between the rabbitfish pairs.

"There has been a long standing debate about whether reciprocal
cooperation can exit in animals that lack the highly developed cognitive and
social skills found in humans and a few species of birds and primates." Dr
Brandl says.

"By showing that fishes, which are commonly considered to be cold,
unsocial, and unintelligent, are capable of negotiating reciprocal cooperative
systems, we provide evidence that cooperation may not be as exclusive as
previously assumed."

Co-author, Prof. Bellwood, also from the Centre of Excellence for Coral
Reef Studies, says that our perception of fishes as cold scaly automans is
slowly changing.

"Our findings should further ignite efforts to understand fishes as
highly developed organisms with complex social behaviours," he says.

"This may also require a shift in how we study and ethically treat
fishes."
