L-001, pterygoplitchtys joselimaianus commonly as gold nugget sailfin pleco. It's not rare but still a nice fish.
Pterygoplitchtys (sailfin plecos and commons are in the family) get large(12-18" and up). They can take care of themselves just fine and do well enough in a cichlid community tank. The are omnivores but do like a good amout of veggies. I usually feed zucchini and yellowsquash - a 12" sailfin can chow down a 6" zucchini in a few hours.
They keep the tank nice and clean but make sure you have enough space.
