Freckled hawkfish (Paracirrhites forsteri)When it comes to keeping hawkfishes in aquaria, one of the more common admonitions is to avoid housing these predators with fish or crustaceans small enough to swallow. For most of the hawkfish species that grace our tanks, which generally have a maximum size somewhere between 3 and 5 inches, only very small tankmates are truly at risk. A noteworthy exception is the freckled hawkfish (Paracirrhites forsteri), which can reach a rather prodigious size and has a mouth to match. You really have to take that warning seriously with this species! That said, P. forsteri is a hardy, easy-to-care-for hawk that makes a worthy aquarium candidate provided tankmates and housing are chosen judiciously.Physical traits P. forsteri has the deep, stout body and high-set eyes, typical of the hawkfishes. Its maximum size is approximately 8½ inches.
Harlequin Tuskfish (Choerodon fasciatus)QuestionTwo 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.
