Mouthbrooding, also known as oral incubation and buccal incubation, is the care given by some groups of animals to their offspring by holding them in the mouth of the parent for extended periods of time.
Asian arowana refers to four species of freshwater fish in the genus Scleropages. Some sources differentiate these varieties into multiple species, while others consider the different strains to belong to a single species, Scleropages formosus. They have several other common names, including Asian bonytongue, dragon fish, and a number of names specific to different varieties. 
Asian arowanas are paternal mouthbrooders. They are slow to reach sexual maturity and difficult to breed in captivity, with successful spawnings typically taking place in large outdoor ponds rather than in aquaria.
