The differences between the
Panaqolus and the Panaque genera
is that the latter has an oval shaped mouth and the
jaws have very large spatulate teeth with a single
cusp, arranged in a v form and Panaqolus
have a small number of spatulate teeth and are also
a smaller genus. Aquarium Care: Peaceful in the aquarium but not suitable
for planted tanks as they are plant eaters. Tank set-up
should contain wood of some description as the Panaques
need this in their diet. Plants will not work too
well as they will be eaten so plenty of wood scattered
around the tank with a few caves for spawning activities
on a sand or small rounded gravel bed will do just
fine. Provide strong aeration due to the higher temperatures
involved. Diet: All Panaques
and also the Panaqolus genera are wood eaters
so would need this in an aquarium set-up. Feed also
vegetable foods such as cucumber, courgette (zucchini)
and sinking tablets. Sexual Differences:
Males have long interopercular spines and their body
is adorned with hair-like spines. Etymology:
The specific name nocturnus:Nocturnus
meaning nocturnal, referring to the dark coloration.
