Multiple pics,all taken at twilight,of one fish in very shallow rocky area on snorkel.Some pics clearly show it is a client of one or more Rockpool Shrimp (Palaemon serenus).

[On that same snorkel,at around the same time,and within the same small area of about a square metre, I also witnessed several Yelloweye Mullet queued as clients, and I had wrongly claimed that I also witnessed -very fleetingly- an Alison's Blue Devil also in client pose.That was actually a Zebrafish in night dress as I very belatedly accepted, per recent update on iNat:)]

Adult in sea-grass on a shore dive. I've included 6 pics of the same individual. The last 3 pics all include a decorator crab,Naxia aurita,on the far side of the subject fish's head.In pics 4 and 5 it and the flat-head are both watching me closely,but in 6th pic the crab has decided to begin discretely moving away from this diver with his flashy camera,while the fish lingers.
