Feeding Question

[naesco]

The sunburst is a very difficult fish to keep and I have not kept them. Frankly my experience long term with any anthias is not good. It requires quiet, peaceful tankmates. low light levels and low flow.
Try tossing in hair algae (her food of choice) which should be mid water and experiment with cyclopseze and smaller pieces of shrimp etc.
Her mouth area may have been injured in fighting against the plastic bag in shipment which is common in small wrasse. (continue the garlic).
