came across this species,
in the flesh so to speak, in Pier Aquatics in Wigan
in the north of England, September 2014 and was instantly
engrossed by the unusual make up of this Loricariid
which resembled a creature from a prehistoric age.
This species has also thick plates and lacks an adipose
group has a total of only nine species distributed
in the Amazon, Paraná,andSáo Francisco basins and some smaller,
coastal streams in south eastern Brazil. The Rhinelepis
group is an assemblage of four genera of medium to
large sized species. This group is unique among Loricariids
for possessing a round (normal) iris versus a bilobed
iris (although it is often hard to see the flap in
bilobed, preserved fishes). The aforementioned Rhinelepsis
group consists ofPogonopoma,
and Rhinelepsis and together they form a
morphological clade within the subfamily Hypostominae.
analysis tells us that there
is a split between the Amazonian genus of Pseudorinelepsis
and the remainder of the genera which occur in
southeastern Brazil. It has been noted that the gill
openings of Rhinelepsis are large which contradicts
that in most Loricariids which are very much restricted.
Rhinelepis strigosa-head view
There are only
two described species of Rhinelepsis the
other being R.
can be told apart from R. aspera by having
rougher scutes with odontodes. The Rhinelepsis
genus have numerous teeth which can be as much as
96 and the stalks are long which is unusual for the
America: Paraná and Uruguay River
basins. Type locality: dans le Parana
et d’autres rXvières de la province de
thick large scutes, large gill openings and lacking
an adipose fin. Round (normal) iris. Head long and
flat. Short fins. Dorsal 11-7, Pectoral fin: 1-6;
Ventrals, 1-5; Anal fin 6 (1 unbranched, 5 branched).
Plain charcoal grey colouration.
Care & Compatibility
Grows rather large and can
be territorial with conspecifics so would need a large
tank to accommodate them. Provide hiding places such
as large pipes. As they have a large metabolic rate,
water changes would need to be adhered to.
Nothing to suggest that there
will be a problem keeping alongside other fishes.
May not be possible
as this genera migrate to spawn, and scatter there
eggs with no parental protection.
Omnivore. Vegetable foods such
as courgette, cucumber etc.
Aquarium staple foods such as tablets, pellets and
