![]() Many of these species are known to bite if handled. If the inflated form of the pufferfish and porcupinefish isn’t enough to put you off going near them, then remember that their mouth parts are capable of crushing hard shells of prey species as well as coral. The boxfish have large, highly patterned scales, often hexagonal in form over much of their body. Their eyes are generally large and appear swollen, while their mouth parts project forward and are described as beaklike. They all have a characteristic way of swimming, using their rear-facing dorsal and anal fins, assisted by mid-body, often quite large pectoral fins, particularly in the porcupinefish. Most of the species in these three groups are very easy to identify. Within this latter group the cowfish also have small horns. The Ostraciidae are encased in a box-like shell of bony plates, with gaps for the eyes, mouth, gills and caudal fin. While the pufferfish have a flexible but prickly skin the porcupinefish have prominent spines, formed from modified scales. ![]() They achieve this by drawing water into a chamber near the stomach. Both the pufferfish and porcupinefish have the capacity to greatly inflate themselves when threatened, preventing attack by predators. Color varies, but many species have light spots and or spines.Feeds mainly on mollusks (hard, powerful teeth enable them to break through mollusk shells) also fed on other invertebrates including sponges and coral.Ĭlose & amp amp amp lt img height="1" width="1" border="0" alt="" src=" amp amp amp amp amp random=1389212343697& amp amp amp amp cv=7& amp amp amp amp fst=1389212343697& amp amp amp amp num=1& amp amp amp amp fmt=1& amp amp amp amp guid=ON& amp amp amp amp u_h=768& amp amp amp amp u_w=1366& amp amp amp amp u_ah=728& amp amp amp amp u_aw=1366& amp amp amp amp u_cd=24& amp amp amp amp u_his=10& amp amp amp amp u_tz=-300& amp amp amp amp u_java=false& amp amp amp amp u_nplug=11& amp amp amp amp u_nmime=27& amp amp amp amp frm=1& amp amp amp amp url=https%3A///> & amp amp lt div style="display:inline "> & amp amp lt img height="1" width="1" style="border-style:none " alt="" src="//googleads.g.doubleclick.You’ll find on this page species belonging to 3 closely related fish families: the Tetraodontidae (pufferfish), the Diodontidae (porcupinefish) and the Ostraciidae (boxfish, trunkfish and cowfish). ![]() Keep only one per tank.Puffers have bodies that are very rounded and often tapered at the mouth and caudal (tail) fin regions. The poison is an alkaloid nerve poison.They will do well in a fish-only aquarium. ![]() Also have a poison in their skin, tissues and organs. These fish also have incredibly strong plated mouth structures that are used to bite and crush even the toughest shells.Almost all puffers are slow swimming fishes with powerful jaws made up of fused teeth feeding on a variety of slow moving and often hard animals. These fish are peaceful towards other fish and do well in a community tank.The family of Puffers is a distinct family marked by their ability to ingest water into the ventral portion of their body causing them to blow up for protection. The Hawaiian Spotted Puffer, Canthigaster jactator, is a small brown colored Puffer covered with circular white spots.
