He cleans everything apart from the dragon wrasse. He seems to have preference to the foxface and the convict though. Can only record for 1 minute on my camera, he was at it for about 15 minutes going from one to the other, say that most people would be pretty bored of 15 minutes of cleaning
My shrimp has a little cave which he hangs from and the fish go in and stop in the entrance while the shrimp cleans them. Will have to get that as it looks pretty cool, like a little service center.
And fish are meant to only have a 2 second memory lol
