The Life of Animals | Discus | Discus belong to the genus Symphysodon, which currently includes three species: The common discus (Symphysodon aequifasciatus), the Heckel discus (Symphysodon discus), and a new species which has been named Symphysodon tarzoo However,
a further investigation published in August 2007 suggested that the genus held the three species: S. aequifasciatus (the green discus), S. haraldi (the blue/brown/common discus) and S. discus (the Heckel discus).
Another characteristic of Symphysodon species is their care for the larvae. As for most cichlids, brood care is highly developed with both the parents caring for the young. Additionally, adult discus produce a secretion through their skin, which the larvae live off during their first few days. This behaviour has also been observed for Uaru species. However when bred in captivity the larvae will tend to live off their parents secretion for up to 2 weeks.
