If the humu and antenna get along, great. But keep a close eye on the humu. I'd add an eel (you have a lot of choices), and a grouper (miniatus, blueline, bluedot), and maybe a harlequin tusk. A clown trigger will eventually outgrow a 100g tank. They are best kept with other large triggers, eels, and groupers. They sometimes do well with large angels too, but I don't reccomend the mix. Bo
