Relevant Information:

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.
