Particularly abundant in coastal creeks and floodplains where it is supported by a certain salinity level. It is vulnerable to a trematode parasite which induces a characteristic cutaneous reaction. Reproduction in captivity has been successful (Ref. 12225). Maximum length questionable (Ref. 38376).
特別地豐富的在海岸的小溪與洪泛區中在那裡它被由一個特定的鹽度支撐。 它是易受傷害的對引誘一個特殊的皮膚反應的一個吸蟲寄生蟲。 人工環境下的繁殖已經是成功的。 (參考文獻 12225) 最大的長度可疑的.(參考文獻 38376)
