Relevant Information: |
The Hypostomus genus has
7 rays to the dorsal fin whereas the similar looking Pterygoplichthys
species have 10 dorsal fin rays. Dorsal spines (total):
2; Dorsal soft rays (total): 7; Anal spines: 1; Anal soft rays:
4. Differs from its congeners by the following combination of
characters: dorsum of head and body and all fins dark grey covered
by numerous rounded cream dots; ventral surface of head and
belly a plain cream color; 66-85 premaxillary/dentary teeth;
cleithral width 3.0-3.4 in SL; abdominal length 3.9-4.5 in SL;
eye diameter 5.2-6.2 in HL; pelvic fin-spine length 3.9-4.5
in SL; caudal peduncle depth 8.3-9.6 in SL; upper caudal-ray
length 2.8-3.6 in SL; lower caudal-ray length 2.4-3.5 in SL;
right mandibular ramus 3.9-4.6 in HL; dorsal spine length with
mean 31.6 % SL; length of right mandibular ramus 3.9-4.6 in
HL; abdominal length 3.9-4.5 in SL; head depth 1.6-1.7 in HL;,
interorbital width 2.6-3.0 in HL; predorsal length 2.3-2.6 in
SL; pectoral-fin spine length 2.8-3.3 in SL; caudal peduncle
length 3.0-3.6 in SL; scutes along lateral line 26-28 (mode
27); scutes between end of dorsal fin to adipose fin 5-6 (mode
6) ; scutes from adipose to caudal fins 3-5 (mode 5), and scutes
from anal to caudal fins 12-14 (mode 14). Aquarium Care:
As with most of this genus, will do well in a larger aquarium,
although this is one of the smaller species in the genera, and
the aquarium well filtered. Water parameters can be quite diverse
for this genera. Diet: Omnivore with a liking
for green, tablet and frozen foods. Remarks:
Found in coastal areas of main river channel with bottom composed
mostly by large boulders of sandstone with patches of sand and
pebbles. Occurs in well oxygenated waters having moderate current
speed, about 0.60 m s-1, water transparency of 1.5-2.40 m and
conductivity of 50.9-59.6 ?S cm-1 . Sympatric with Hypostomus
commersoni, H.
cochliodon, H. uruguayensis, H.
latifrons, H. ternetzi, H.
luteomaculatus, H. microstomus, and H.
boulengeri. |
