Has anyone noticed their clownfish being curious of the sand-sifting diamond goby and try to imitate what it does with the sand? My black/white ocellaris clown follows him around out of curiosity, but never aggressive against it, and will grab a mouthful of sand and spit it out which seems to be imitating what the goby does. He/she is also curious of the entrance to the sand cave under the live rock and pokes its face in it sometimes. Very entertaining to watch!
