f you would like to venture
into the breeding of the family Loricariidae here
is a species which you can get your teeth into and
start you off and hopefully take you on a journey
to the more fancier L-numbers of the Panaque,
Peckoltia and Hypancistrus genera's. Along
with the various Rineloricaria and Loricaria
the genus Ancistrus is one of the easiest
to begin with
and the many species in this genera have been bred
for many years, and one of them is this months (June
2012) factsheet subject, the Three ray bristlenose
catfish, Ancistrus triradiatus.
Why the "Three
ray bristlenose catfish"?. This is brought about
by the three soft rays in the anal fin peculiar to
this species, ie: triradiatus, meaning three
Below is an image
of the orange eggs in pipework. Unlike the Rineloricaria/Loricaria
genera who like an open pipe or cave at both ends
the Ancistrus males prefer to have one end
blocked off although this does not stop a determined
pair if it is an open cave, but it does give better
options for spawning.
- orange eggs
For your tank
set up you can provide a sand substrate with driftwood
and pipwork with closed ends. Water circulation for
oxygen intake is a benefit.
ray bristlenose catfish.
Colombia, Middle and
lower Orinoco River tributaries; Valencia Lake and
Los Guayos River basin; southern tributaries of Lake
Maracaibo basin. Type locality:Quebrada Cramalote, Villavicencio; Andes
east of Bogotá, upper Meta basin, Colombia.
Males possess large bushy tentacles
to the mouth area, the females are very much smaller.
Three rays to the anal fins.
Variations on mottled brown
with the fins sporting brown banding/lines. The
juveniles lack the light caudal fin edging that
is found in a lot of aquarium bred species of Ancistrus.
Care & Compatibility
As with most of this genus
it will do well in an aquarium where it will wipe
out any algae. You can house with most of the Tropical
fish species that are found in the hobby today. Try
not to put too many bottom living species with them
as this limits there tendancy to concentrate on producing
to breed where the female will deposit her eggs, up
to 100, in a confined space such as pipe work. The
juveniles can be raied on tablet and vegetable foods.
Males have, as in this genera,
bushy tentacles to the mouth area and the females have
them very small.
Feed vegetable foods such as
lettuce, cucumber and courgette (zucchini). Will eat
most aquarium fare.
Anal fin:The fin forward from the anal cavity. Caudal fin: The tail.
Ancistrus:With barbed hooks, (hooked spines). triradiatus: three rays.
