Biology     Glossary (e.g. epibenthic)

Facultative air-breathing in the genus (Ref. 126274 ); Adults occur mainly in swamps and similar still, often turbid waters (e.g. irrigation ditches). Form loose schools of about ten individuals of approximately the same size. Enter brackish water. Can survive temperatures up to 39.8°C (Ref. 7256 ). An omnivore with nocturnal feeding habits. Oviparous, distinct pairing possibly like other members of the same family (Ref. 205 ). 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.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Eggs of about 2 mm diameter are laid in lumps in a gravel nest. The parents guard the eggs and the youngs.

Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00437 (0.00195 - 0.00975), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.3   ±0.4 se; based on size and trophs of closest relatives Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec < 10,000). Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (10 of 100). Price category (Ref. 80766 ):   Unknown .
