'Gelek'
anemone shrimp Ancylomenes holthuisi Family Palaemonidae updated
Jan 2020Where
seen? This slender shrimp is rarely seen, sometimes in large sea anemones. It 'dances'
in a waggling way: 'gelek' means dance in Malay.
Features: About 2cm. Body almost
transparent with a brown-spotted white patch behind its head, a white
patch on its 'butt', with purplish-blue tips on its tail and pincers.
Does it 'clean' fish? A filefish
was once observed close to an anemone shrimp for some time. Could
it be expecting the shrimp to clean it?
What does it eat? Anemone shrimps
do not appear to eat the host anemone or off the anemone's fluids.
Instead, they are believed to shelter in the anemone for protection
and may feed on left overs. The shrimps have often been seen "hanging"
over the edge of their anemone home with their pincers extended.
