Yellow Watchman Goby violating open brain

[Aquaman101]

So, it appears my yellow watchman goby has decided it likes the open brain in my tank.

He parks right in the middle of one of the crevices of the brain and just hangs out there.

Anyone seen such a thing? The brain doesn't seem to mind.

Mine will sit on my clam and the clam never closes on it.
