The Threadfin, or Auriga, butterfly is one of the more durable and readily available butterfly fish. It will accept a wide range of aquarium foods and can withstand some neglect, for a butterfly. Of course, optimal water quality is required to ensure its good health. Once acclimated, it tends to be one of the more bold butterflies. It can be employed to clean live rock of aiptasia anemones; however, it will also feed on some of the more desirable invertebrates living on the rock, like fan worms.
