I have them both in my tank (75 gal) as long as they have places to hide... also if adding one make sure to rearrang your tank so the tang won't beat them up. I also have 3 skunk clowns,3 percula clowns,1 Mandren,1 6-line wrasse,6 pepperment shrimp,10 turbo's,30 hermits,3 raccoons and a pair of Mollies, brittle star and 5 anemones.
