The Pygmy Tuberculated Frogfish (Antennatus tuberosus) is a very fascinating addition to any aquarium. Frogfish are actually a type of angler fish, and do have a small antenna that they use to attract small crustaceans. They perch on branching corals and rocks in search of food and are very good at camoflage. They may eat frozen food in time, but usually only eat live food to start. Baby brine, copepods, and other small crustaceans are ideal for smaller specimen, and larger ones will feed on small fish/crustaceans. They are capable of eating fish nearly equal their own length, so use caution when housing with small damsels or clownfish.   The Pygmy Tuberculated Frogfish Care Guide From SaltWaterFish.com  Introducing the Pygmy Tuberculated Frogfish, a fascinating and captivating addition to saltwater marine aquariums.
