The Geometric Pygmy Hawkfish, Plectranthias sp., also known as the Geometric Pygmy Perchlet or the Hi Fin Perchlet, is one of the most visually unique hawkfish species available. It is also one of the more rare aquarium fish available to home aquarists. The Geometric Pygmy Hawkfish has a bright red coat broken up into beautiful geometric shapes by bands. The Geometric Hawkfish is an active reef dweller and will not harm corals but may bother small shrimp or snails. A tight lid is suggested for your tank to prevent the Geometric Pygmy Hawkfish from escaping. They will grow to a maximum size of about 2 inches. They are great reef dwellers in community tanks and are best kept with plentiful open live rock allowing them places to hide. Their natural diet is zooplankton but can be fed a variety of prepared foods including meaty frozen shrimps and quality flake food.
