back at the last 23 years of ScotCat factsheets, this
is the one genera that has been noticeable by its
absence which to me has been a transgression on my
part as there are countless species from this genus,
and although most of them grow quite large they are
on the whole peaceful albeit a bit boisterous in the
confines of an aquarium.
in this genera are spotted and brown H. regani
stands out as one of the most beautiful especially
as sub-adults, and can look very impressive when out
in the open especially when showing its high dorsal
which differentiates it from other similar looking
- showing the
large dorsal fin
Hypostomus includes species of medium to large
body size (50cm) and has 7 rays to the dorsal fin
whereas the similar looking Pterygoplichthys
species have 10 dorsal fin rays. There are a few similarly
coloured species that look like H. regani
such as H.
strigaticeps and H. variipictuus but
as earlier mentioned the high dorsal fin with light
coloured rays tells it apart from these aforementioned
São Paulo, Rio Pardo. Paraná, Paraguay
and Uruguay River basin.
H. regani (Ihering, 1905) was described from
the Rio Piracicaba, upper Rio Paraná basin,
it was collected in streams flowing into the Rio Paraguay
basin, in northern Paraguay (Weber et al., 1992) as
well as in the Rio Manso basin, upper Rio Paraguay
basin (Veríssimo et al., 2005; Zawadzki et
Giant White Spot Pleco
Paulo, Rio Pardo. Paraná, Paraguay and Uruguay
Absence of evertible odontodes
on the interoperculum, and non-evertible odontodes
on the head or body; dorsal fin with seven rays. Papillae
poorly developed and irregular in size and shape.
Abdomen covered with plates or completely uncovered;
caudal fin bifurcated (Hypostomus genera).
Youngsters have an overall
black or dark colouration with gold/yellow spots.
Adults tend to be more of a brown body colouration
with paler spots.
Care & Compatibility
Peaceful but as it is territorial
only keep one species to a tank. Tank layout should
have bogwood and tough plants as if the plants are
of a soft variety they will eat them if not given
an adequate vegetable diet. Grows large so a spacious
aquarium of 6ft (180cm) or over would need to be catered
for. As this genus in the main are messy eaters, good
water quality and filtration would need to be adhered
to. Lower water temperatures are beneficial to this
species. Will coexist with most species but may be
aggresive with conspecifics.
recorded in the aquarium due to its large adult size.
grow larger and have longer fins, especially the pectoral
and caudal fins.
Algae, and vegetable foods
such as cucumber and courgette (zucchini). Will also
take frozen foods as a treat and sinking tablet foods.
Dorsal fin:The primary
rayed fin(s) on top of the body. Odontodes: Hair - like stuctures
on the body. Papillae:A small
fleshy projection, plural papillae. Pectoral fins:
The paired fins just behind the head.
Hypo = underneath;stomus = mouth.(mouth
