Need to do a research paper...

[Nate]

I would maybe consider focusing on the relationship between cleaner fish/shrimp and fish. This would be easy to observe, and lost to write about.

I would also consider the classic clowns/anemones.

Tangs would also work, you could talk about the difference in communication and relationships between aquaria tangs and wild tangs as well....

As for papers, not too sure, you will definently have to do some digging on this...
