Similar 120g - 24x24x48. My current fish - Yellow eyed Kole Tang one spot Fox Face Starry Blenny two Ocellaris clowns. I'd also like to add a Purple Tang. Perhaps in a few months. I'd like to get a purple about half the size of the Kole. My working theory - too small for the Kole to be all territorial about and the purple hopefully won't want to be the boss. So, is there room? I'd appreciate any thoughts on achieving this fish grouping. Tank is mostly peaceful now. The Kole wants to be boss. Tries to bully Fox Face but FF goes all spike and tang mellows. Tang also chases the Blenny. No damage has been done.
