Help identifying coral

[Resilient]

I forgot to write down the names like I usually do when I get coral.

This guy isn't doing super well compared to other corals I got, would like to figure out what it is to see if maybe it has too much light or flow isn't good.

candy cane coral, aka trumpet coral

possibly Astraeosmilia tumida? how large are the corallites?
