Harlequin Tuskfish (Choerodon fasciatus)

Question: Two weeks ago, I added a harlequin tuskfish to my 90-gallon reef tank with the understanding that it’s a peaceful fish. Then this morning, the stupid thing ate my skunk cleaner shrimp right in front of me! Was I misinformed about this fish’s temperament? Eating tankmates whole seems like pretty aggressive behavior to me. Also, I was under the impression that predatory fish usually leave cleaner shrimp alone because they recognize that they’re helpful. Is that not the case?” – Submitted by Jen

Answer: I don’t know that I’d say you’ve been misinformed about this species’ temperament exactly, but it may be that you’ve misinterpreted or misapplied a few terms here. MORE
