Differs
from all other species of Mystus in having eyes lateral,
rather than dorsolateral, so that they are about equally visible
viewed either from above or from below head (in other species eyes
usually cannot be seen at all from directly below). Mouth nearly
terminal, less downturned than in any other species of striped
Mystus. Serrae of pectoral spine smaller
and less erect than in any other striped Mystus.
Adipose fin short but very high, originating far behind dorsal
fin, its length about twice and its height slightly less than
eye diameter. Gill rakers increase in number throughout life faster
than in any other Mystus. The anal fin has slightly more
rays (13-15) than other striped Mystus of Thailand (usually
12 or less), and its posterior border is distinctly falcate. Cranial
fontanel extends posteriorly to about midway between level of posterior
border of eye and base of supraoccipital process. Maxillary barbel
extends posteriorly to beyond anal fin or to end of middle caudal
fin rays. Side of body with 3 faint dark and 2 whitish stripes.
Often found in mixed schools with M. multiradiatus which
congregate around tree limbs and other solid objects, browsing the
hard surfaces for zooplankton, aquatic insects, crustaceans and
rotifers. Moves into flooded forests during the rainy season and
returns to rivers in November and December in the lower Mekong.
Oviparous, distinct pairing possibly like other members of the same
family. |
