schools of about ten individuals of approximately
the same size. Enter brackish water. Can survive temperatures
up to 39.8°C. Very easily maintained in captivity.
Sympatric with H. fossilis which is more
abundant in the type locality. Best method of catch
is dewatering of small water holes during drought
period. Diet: An omnivore with nocturnal
feeding habits. Reproduction: Oviparous,
distinct pairing possibly like other members of the
same family. According to the IUCN Red List this species
ic classed as vulnerable. Remarks:
The current status from Eschmeyer's Catalog of Fishes
