Peacock Sailfin Plecostomus L347

L347 is a large peacock sailfin pleco with a tall dorsal fin and an ornate spotted or reticulated pattern over the body and fins. Its adult requirements match other giant sailfin plecos.

L347 is an undescribed Pterygoplichthys form reported from the Rio do Pará. It can resemble L165 and other sailfin plecos, so provenance and the retained L-number are important.

External sex differences are subtle. Mature males may develop a broader head, stronger pectoral odontodes and a more pointed genital papilla, while females may become fuller through the abdomen.

Plan for a very large adult from the beginning, with extensive floor space, powerful filtration, strong oxygenation and sturdy decor. Heavy waste production, plant disturbance and the need for open turning room make small community tanks unsuitable.

Usually calm toward free-swimming fish but forceful around food and shelter. Adults may become territorial with other large plecos and can shift loose decor.

Usually peaceful toward unrelated midwater fish but may outcompete slower bottom dwellers for food and shelter.

Adults, especially males, may defend preferred resting or feeding areas from similarly shaped loricariids.

Choose robust, non-aggressive companions and avoid crowded bottom communities. Slow broad-bodied fish should be monitored in case the pleco attempts to rasp their slime coat.

Maintain warm, clean, well-oxygenated water with powerful filtration. The fish is active for its size and requires a long aquarium rather than only high water volume.

Offer a varied omnivorous diet with vegetable-based sinking foods, fresh vegetables, biofilm and measured animal protein. Natural algae and leftovers are not enough for a growing adult.

Feed after lights dim and distribute food near more than one shelter. Remove uneaten vegetables and rich foods before they affect water quality.

Home-aquarium breeding is generally impractical because Pterygoplichthys normally excavate deep nesting burrows. Commercial reproduction uses systems far larger than an ordinary aquarium.
