is distinguished by the following characters: 14-16
branchiostegal rays; 14-16 gill rakers on first branchial
arch; 68-73 anal fin rays; small gape extending to
anterior margin of eye; pelvic fin length 8.9-10.6%
SL; small eye, 8.7-10.1% HL; maxillary barbels reaching
to middle of pectoral-fin base; rounded pectoral fin
in which the fourth branched pectoral ray is the longest;
pectoral spine length 14.3-16.7% SL; dark colored
body with a few pale spots forming a mottled pattern;
and 63-65 vertebrae. Adults feed strictly on fishes.
Enters the flooded forest during high water and stays
near the edge of the forest during low water. Migrates
into smaller streams to spawn. Oviparous, distinct
pairing possibly like other members of the same family.
Only juveniles can be kept in aquaria and fed on tablet
food, beef heart and similar foods. Adult fish are
not deemed suitable for aquarium keeping due to the
size, verocity and its feeding needs for living fish.
Cited in Fishbase and other internet sources as Wallago
but in Eschmeyer's Catalog of Fishes the current status
is Wallagoniamicropogon (Ng, 2004)
(2018). The diferences
between Wallago and Wallagonia are
complex and are due to the different bone structures.
Wallagonia was placed by Myers (1948) and
nearly all subsequent authors as a junior synonym
of Wallago, but it is was later recognised
as a distinct genus by Roberts, T. R. 2014.
