Maze Plecostomus L164

L164 is a large sailfin pleco with a tall dorsal fin and a maze-like pattern of dark lines over a paler body. Its adult size and waste output are comparable to other giant Pterygoplichthys.

L164 is an undescribed Pterygoplichthys form associated with the Tefé region. Keep it separate from L165 P. gibbiceps and L083 P. xinguensis even when commercial fish appear similar.

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.

A large warm-water form that needs stable, oxygen-rich water and exceptional filtration. Soft to moderately mineralised water is suitable when changes are gradual.

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.
