Whip coral shrimp

Macro day today! The whip coral shrimp is a type of cleaner shrimp, and it eats plankton, algae, and parasites.
These two shrimps are a few mm long, and so camouflaged they take the same colour and texture as their surrounding corals, gripping the whip coral which is like a stiff shoe lace hanging in the water from the sea bed.
My old eyes are now struggling to find these.
