Yeah, nem should match setup, and if sps, most likely has high flow/light.
I had about 40x turnover in my 180g sps/mixed.
I made the mistake of getting both LTA and sebae many years ago, sebae could take all the light and flow I could put out, but LTA was much more sensitive, not fond of heavy light/flow at all.
I got away w/ it by putting in a cavey area, so it could pull in/out as needed.
I agree both are sand dwellars and easier to control, and my LTA was really easy once I knew what it liked, and placed in right area it wouldn't venture.
Keep in mind, they both get big, and will take up coral space, need lots of room in between them and corals.
