Ancistrus claro Knaack,
new kid on the block, so to speak,
is this small pretty Ancistrus from the Rio Claro in the
Mato Grosso area on the South Western tip of Brazil. You will find
this species in the Aqualog all L-Numbers as LDA08 and was first
imported into Germany in 1993 and subsequently was given this moniker
by the German publication "Das Aquarium". The holotype
resides in the Berlin Zoological Museum.
The common name of the "Gold Marble
Bristlenose Catfish" is I think a bit misleading as if you
have ever kept this species they change colour on a regular basis,
whether they are resting on the substrate, on a piece of wood
or rockwork. They seem to take their colouration from their surroundings
and a better common name would be " The Chameleon Bristlenose
As mentioned earlier, they reside in the Rio Claro and the type
locality mentions "above the bridge in the direction of Chappada
dos Guimaraes", this is not not far from the town of Cuiaba
. It has been collected in the Coxipo River and other western
tributaries and the Copixo is the area that is stated in the type
locality. Its habitats consist of fast flowing waters with little
vegetation among and under rocks.
This description of its habitat gives us an insight on how best
to keep this species, providing plenty of water movement and caves/pipes
with plant life only as a personal addition to the aquarium.
The above picture shows a young pair with
the male to the front with the marble markings to the body and
head area. The female is darker and has more of a spotted pattern
and has small bristles compared to the young male who will eventually
sport the more traditional male Ancistrus head dress
of larger and branched bristles.
This is an Ancistrus species which you will see quite
often during the day, either clamped to the tank walls or sitting
on or underneath their favourite position of flat stonework.

its favourite positions of rock clinging.

the flat stone.
|| Showing the mouth structure
shape with both sexes sporting bristles to the head area with
the male having the larger and more impressive tentacles.
Base colour of brown with gold marble reticulations
in the male. The female has a darker colouration which comprises
of a more dotted pattern. Both sexes have banding to the caudal,
dorsal and pectoral fins and a white ventral region.
Quite an easy species to keep as long as there
is adequate aeration in the aquarium and giving them a choice of
pipes, stones or rockwork.
As per the Ancistrus family in neutral
to mildly alkaline water. Will spawn in caves/pipes and the eggs
are yellow, large, and can number to about 40 in a good spawning.
They are mostly omnivores with a liking for
most foods. I find that they will eat courgette(zucchini) but they
are not as keen on it as your usual bog standard Ancistrus
species are. Will eat most flake and worm foods and have a particular
fondness of algae discs.
