The Colored Angler is a great choice for any reef aquarium without smaller fishes, which the Angler would probably eat. It will not bother any corals, clams, or larger invertebrates. The Colored Angler can change colors to camouflage itself with its surroundings appearing to blend in with the reef. If you ever have trouble feeding the Angler try putting several Green Chromis or Damsels in the tank to act as feeder fish, they are reef safe and will add a splash of color to your reef until eaten. After your Angler is well acclimated to your tank try offering it pieces of defrosted shrimp on the end of a feeder stick. Just wiggle the shrimp in front of its mouth until it eats it. The first time is usually the hardest, once the Angler tries a piece of shrimp it seems to begin to recognize the feeder stick, and the shrimp as a good easy meal.
