Description:
Glyptothorax is distinguished from all other
sisorid genera by having an adhesive apparatus on
the thorax with with grooves parallel or oblique to
the longitudinal axis of the body (vs. thoracic adhesive
grooves transverse to the longitudinal axis of the
body in Pseudecheneis, and thoracic adhesive
apparatus absent in all other genera).
Glyptothorax silviae is generally distinct
in having long, or approximately as wide as long,
thoracic adhesive apparatus (vs. short in G. kurdistanicus);
head and flank without tubercles (vs. present in G.
armeniacus and G. cous) and warts (vs.
present in G. daemon). Medial pit of thoracic
adhesive apparatus without striae (vs. present in
G. steindachneri). Colouration: Upper
head, back and flank with few or many dark-brown spots
and/or blotches (vs. in G. pallens) (Sayyadzadeh
et al 2022). Aquarium Care:
Glyptothorax are susceptible to degraded
water quality since they come from pristine water
conditions and can not cope with even the slightest
changes. The same water conditions should be maintained
in the home aquaria while keeping them clean,cool
with high dissolved oxygen waters. A hillstream setup
with sand, pebbles and rocks is ideal for them with
lots of hiding spaces (Mishra, A.). Diet:
They feed on insect larvae, smaller invertebrates
and crustaceans in nature. In home acquaria they should
be fed with live foods such as bloodworms, brine shrimps,
tubifex, though after acclimating to tank environments
they are also known to take sinking pellets (Mishra,
A.).
