Temperament: Very peaceful species that will get along well with tropical community fish and cichlids. They will squabble with other similar sized Pleco's and bottom feeders if not given enough room to establish a suitable territory. These territorial battles tend not to be too violent.
Diet & Nutrition: Omnivorous, they will eat a variety of plant material and meaty food they find in the aquarium. They are picky eaters, but you should offer them a balanced mix of algae, decaying plant matter, and meat-based meals.
Breeding and Spawning: Plecos species lay eggs and spawn on the side of artificial caves. In the wild, the male plecos guard the eggs until they hatch. However, to increase the egg survival rates in a tank, remove the fully grown Galaxy Pleco from the breeding tank. Then, eggs would hatch within five to seven days.
Gender: Adult males have a much longer and broader head with small odontodes on the sides of head, more odontodes on pectoral fin spine and on the whole body, a bigger dorsal fin and normally a prettier coloration.
