L 46 Hypancistrus zebra
by Shane Linder
Hypancistrus zebra comes from the Rio Xingu in Brazil. Before it
was described in 1991 it was assigned the Datz L number L 46. I have never
seen any solid info on the water chemistry of the Rio Xingu, but it is not
that important as H. zebra seems to do well in just about any water
provided it is high in oxygen and temperature. A temp of 72F is way to
low. The tank should be kept around 80F. Since at higher temps you have
less oxygen, you need to compensate with increased aeration/circulation.
The aquascape of the Xingu is well known. The water, where H.
zebra is found, is fast flowing. The river is full of rocks of many sizes
and some fine sand between them. The ideal H. zebra tank would be set up
to resemble a Rift Lake tank more than what we think of as a "South
American" biotope. The fish live and spawn in the caves and cracks of the
rocks. Unlike many other loricariids, H. zebra is more of a carnivore than
an algae eater. Provide mainly meaty foods. I would provide some
driftwood, but many people claim that their H. zebras never touch the
stuff. Better safe than sorry. pH and DH do not seem to matter since the
fish has been spawned in all types of water (including a Rift Lake tank).
