Just my first coral, star polyps, this afternoon.
Acclimed and placed it in a quarantine tank after i got home. When i turned on the lights i saw some claws hastily retracting into a crevice.. is a freshwater dip advisable?
some parts of the piece has strands of brown stuff growing on it. It resembles brown human hair, should i remove those as well?
some pics of the brown algae (i think) below for ref.
