Relevant Information: |
Typical Ancistrus shape
with both sexes sporting bristles to the head area with the
male having the larger and more impressive tentacles.
Aquarium Care: 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. Breeding:
As per the Ancistrus family in neutral to mildly alkaline
water. Will spawn in caves/pipes. Remarks:
Ancistrus tolima has a very restricted range (extent
of EOO = 160 km²). It lives in a single creek of about
10 km² that is isolated by a dam. The species is genetically
isolated. There is subsistence agriculture in the area, and
run-off of agrochemicals is affecting habitat quality. The creek
is a dry area that is affected by sudden temperature changes
and thus highly sensitive to climate change. For instance, during
El Niño event, water quantity in the creek can be reduced
to 20% of normal levels. Hence, the species is listed as Endangered.
The creek in which this species lives flows into another creek,
which in turn flows into a dam that was built in 1971 (the species
was discovered in 2005 but only described in 2013). In other
words, the species is genetically isolated and restricted to
an area of about 10 km² because there is no connection
with the main river (Magdalena). There is subsistence agriculture
in the area of the creek; the run-off of agrochemicals affects
habitat quality. The area is the northernmost limit of the tropical
dry forest on the western slope of the eastern Cordillera; it
is a dry area that is affected by sudden temperature changes
and thus highly sensitive to climate change. For instance, during
El Niño events water quantity in the creek can be reduced
to 20% of normal levels. (IUCN Red List). It has been found
in a creek with sand and gravel substrate, abundant organic
material, and steep banks with little shoreline vegetation (Taphorn
et al. 2013). |
