It’s one of those corals that is really hard to definitively ID (especially from a photo), my best guesses would be a Favites or a chalice (which is a generic term for corals from like 8 different genera, chalices can be really difficult to definitively ID, some like the ‘Hollywood Stunner’ are easy, but some can be really tough). It looks a lot like the TSA Spicy Lemon Micro Favia, which isn’t a Favia (I realize that not that helpful, but at least you know what it isn’t, lol). It would be great if these vendors would put more effort into properly IDing stuff, and I get why they don’t (mostly to make it easier for people to search for common names), but they could at least put a tag with the actual species. I would maybe email TSA and ask if they know the actual species of the Spicy Lemon Favia, couldn’t hurt to see if they maybe have an idea.
