I have heard of the rare occasion of a mature (spotless) Domino Damsel hosting in a carpet anemone, but I have a 1.5" Domino (with 3 spots) and every night it goes to sleep in a long tentacle anemone. It pays no attention to it all day, just at night. Anyone else heard of a Domino doing this? My Occelaris Clown is so confused that it started hosting in a large hammer coral.
