cleaner gobies and clients

[panaman]

Hello all,

I have a question for all you avid aquarist who keep neon cleaner gobies:

Has anyone seen a Caribbean cleaner goby (Elacatinus sp) clean or try to clean a fish that is not from the Caribbean? In other words, has anyone seen a Caribbean cleaner goby clean a fish with which it has not co-evolved?

Please include the species of both partners and a descritption of the event.

Thanks!
