Colored Angler (Antennarius sp.) Care
The Colored Angler, Antennarius sp., comes from various parts of the world including the Pacific, Atlantic, and Indian Oceans. These fish are primarily burnt orange to bright red in color and they can change color to match their environment. These unusual fish are not active swimmers and remain still much of the time waiting for prey to come close enough to attack. They use a bait-like appendage, called the esca, to attract prey within striking distance. They use their pectoral fins like feet to move using a walking motion.
Anglers are carnivores and should be fed a diet of small feeder shrimp and fish, preferably marine species. They may eat small tankmates, including fish and inverts. They should be fed at least a couple of times a week.
They do well in an aquarium in the 30-gallon range. In a reef tank with lots of rock work, you may never see them because they are masters of disguise.
They are considered reef safe with caution because although they will not bother coral, they may eat smaller inverts and fish.
