Food and feeding

Although these fish are classed as omnivores, most of their diet will need to contain vegetable matter. They will require algae wafers, spinach, and peas etc. to keep them healthy. Lyre Tail Pleco’s should also be offered meaty foods like mysis and blood worms.


South America; Lyre Tail Pleco’s are to be found in the Amazonian River Basins


Males tend to have more spines on their fins than the females.


As of yet there are no reported cases of this fish breeding in the aquarium.


The expected life span for Lyre Tail Pleco’s is 5-8 years.

Short description

Adult specimens of these fish can grow up to 70cm in length. They require a very large tank to keep them happy with lots of hiding places. Filtration need to be very high as they do produce a lot of waste, regular water changes are also a must. They are aggressive to other species of catfish; this has resulted in death of one of the fish in the past.
