identification Help With Coral

[saboken]

I got these at Petco can anyone ID these? know what there needs are? they were perfect when bagged up but I think the guy was a bit rough with them and damaged/killed the center of the carpet, it's starting to look like a doughnut dying from the center out, I have 10 red leg scarlet hermits that go in and remove most of the dead tissue and I try to use gentle blasts of water to blow away and detris that may build up.

Thanks for the info.Petco had them mislabeled as with a lot of things, I just moved them closer to the Lighting and an a higher flow area, does anyone know if a blunt-end sea hare dolabella auricularia is safe with it? the sea hare is only temporary another week or 2
