You can identify a Pterygoplichthys species
from Hypostomus for example due to the many
more rays in the dorsal fin, which can be up to 10
or over. They also have nasal flutes on the nose.
the status of this species it will be reasonably peaceful,
if large species, which will need a good sized aquarium
starting of with a 3 footer (90cm) when small and
progressing to a larger tank with good external filtration
to facilitate a good oxygen content, as it excretes
copious amounts of waste if fed properly on vegetable
matter. If the water quality is not adhered to, small
holes can appear in the fin membranes. You will notice
when your water quality is not up to the mark as they
"hang" in the water just of their fins,
from the substrate, which means 'get that water change
done'. It is kind to plants in the aquarium, the only
problem is when it gets bigger and can uproot them
in its conquest around the tank. Very hardy species
which will do well in normal aquarium temperatures. Diet: They are mostly vegetarian
with algae being their number one source of food but
to keep a large fish fed on algae alone is impossible
so you can feed also, spinach, blanched lettuce, cucumber,
courgette (zucchini) and also non veg food such as
tablets and prawns.
