Hi,

I am searching for an article about the cleaner fish.
The content is:
female cleaner check other harems on their social structure. If the structure allows to become fast the next dominant male. It says that females that often check other harems increase their chance to do so.

I think that the article is wtitten by A. Grutter but I am not absolutely sure. I need the article as refference for a paper I have to write.

Can anybody help me???

Would be great
Thanks
Johannes
