Description:
Ancistrus patronus differs from all other
Ancistrus in the region except A.
lithurgicus, A.
macrophthalmus, A.
maximus and A.
nudiceps by having
an entirely black body with tiny white to golden dots;
from A.
leoniby having the abdomen almost as dark as the sides
(vs. much lighter); from A. nudiceps by reaching
a much smaller maximum size (86 vs.138 mm SL), by
having the distance between the anteromedial plate
and the snout greater than or equal to the distance
between the anteromedial plate and a line formed by
the anterior margins of the nasal apertures (vs. less
than); and from A. leoni, A. lithurgicus,
and A. macrophthalmus by being deepbodied
(vs. flattened), by having the median plate below
the posterior edge of the adipose-fin membrane about
twice as tall as wide (vs. just slightly taller than),
and by the eyes being laterally placed (vs. dorsolaterally
placed in A. lithurgicus and almost completely
dorsally placed in A. macrophthalmus (Souza,
LS de. et al). Colouration:Body and fins jet black with tiny white dots.
First dorsal-fin membrane with dark pigment near base.
Upper and lower tips of caudal fin sometimes white
or cream coloured. Aquarium Care:
The Ancistrus genera make good community
fish where they do not grow too big for the aquarium.
Some species have different requirements in the aquarium
so best to read up on the species you have whereas
if they need higher oxygen requirements or not, or
if they prefer cooler waters if they originate from
the southern parts of South America against the species
from further up north. Diet: Vegetable
foods such as cucumber and courgette and also tablet
and meaty foods. Reproduction: The
female lays her eggs in caves or crevices... that
the male has chosen and cleaned.... as a cluster.
The male usually then guards the eggs after ejecting
the female. The fry then cling to the sides of the
cave and when they use up their yolk sac, which is
around the four to seven day period, they will be
ready to feed on infusuria, vegetable matter, brine
shrimp naupli or micro worms. In a community tank
a few will survive if enough hiding places are afforded
to them. Etomology: The specific
name patronus: Named for good fathers. Patronus
is Latin for protector or defender and is derived
from pater for father. (Souza, LS de. et al).
