Different from M. barrae
in that it has small spots wheras M. barrae
has a line pattern to the body and also from M.
which has larger spots. The Megalancistrus genera
are closely related to Pseudacanthicus and
have, in both sexes, their bodies covered in spiny
odontodes but Megalancistrus has more soft
rays in the dorsal ( between 10 and 12). Sexual
Differences: Males have a broader head, longer
pectoral fins, slender body and the odontodes are
longer, especially around the gill cover area.
Aquarium Care: Will need a very large aquarium
as they are a territorial species and will also need
hiding places such as driftwood and large caves. Diet:
Omnivore, frozen foods such as brine shrimp, mosquito
larvae, shrimps, mussels and fish flesh and also good
quality dried foods. They will also eat green foods
in the aquarium.
