I have red and a blue linckia stars in my tank, but I’m mainly worried about the red. I came home today to a bunch of stringy looking brown stuff hanging from his mouth. He is also spitting red foot like pieces off of him. I’ve heard this could be it releasing / regenerating damaged feet or a mating response. I added the blue linckia star a few days ago and was wondering if that could be the reason for this behavior. The red had been in my tank for over a month and was drip acclimated for over an hour as well as making sure never to remove from the water.
