Collectively known as sea squirts, tunicates etc, as to the exact species, not a clue.

They are filter feeders, i only know this from the british variety ofcorce but they certainly look healthy in your tank whatever species they are!

The Sea squirt is an interesting and prized marine reef dweller; in nature it filters thousands of liters’ of water per day, in an aquarium phytoplankton should be added to boost it feeding. The Sea squirt requires to strong water flow and lighting is immaterial.

Polycarpa aurata

Adult speimens do not do well, needs daily feeds of liquid invert food.
