L244 Black Spotted Flyer Pleco
Remarks: The L244 Pleco (Pseudolithoxus dumus), nicknamed the Dumus Pleco or Black Spotted Flyer Pleco, comes from the Colombian Orinoco and Atabapo Rivers. They are primarily an algae grazer and need a high content of biofilm in the tank. They are dark brown with small black spots covering their entire body and fins. As they age, their pectoral fins lengthen to up to 2″ long and grow long odontodes, as seen in the photo. From above, these Flyer Plecos really stand out from other Loricariids!

This pleco is a striking addition to my tank. The black spots stand out well against the dark brown body. It’s active and constantly grazing on algae. After a few weeks, I noticed its fins grew longer, which is exactly what the description mentioned. I keep it in a 55-gallon tank with good biofilm buildup and it’s doing well.

The coloration is very distinct and it looks great in the tank. I was worried about algae control, but it’s been eating consistently. The fins are still developing, and I expect them to grow longer over time. Needs a stable pH and good biofilm, which I’ve provided.

I bought this pleco for its unique appearance. It’s not just a typical pleco — the black spots and long fins make it stand out. It’s active and helps keep the glass clean. I’ve maintained a stable pH and moderate hardness, and it’s thriving.
