(15)L191 Dull-Eyed Royal Pleco 2''

The L191 pleco, also known as the Dull-Eyed Royal Pleco or Broken Line Royal Pleco, is a large, wood-eating armored catfish. Its scientific name is Panaque sp., as it has not been formally described.

• Body: They have a stout, "football-shaped" body with thick, bony armor plates.
• Coloration: The L191 has a dark, moss-green base color covered in irregular, broken black lines.
• Eyes: The fish gets its "dull-eyed" name from its typically dark or grayish eyes, which are less vibrant than those of some other Panaque species.
• Size: The L191 pleco can grow to an impressive adult size of 15–20 inches, though its growth is slow and heavily influenced by diet. 

• Tank size: Due to their large adult size, a minimum tank size of 125 gallons is recommended, with 180 gallons or more being ideal. Tank length and width are more important than height.
• Water parameters: L191s are hardy but require stable and well-oxygenated water with good flow.
  • Temperature: 74–82°F (23–28°C).
  • pH: 6.5–7.5.
• Aquascaping: Driftwood is essential for this species. It not only provides a hiding spot but is a critical part of their diet. They will also appreciate large rocks and caves for hiding.
• Filtration: Powerful filtration is necessary to handle the large amount of waste they produce from eating driftwood and other foods. 

• Driftwood: Soft driftwood, such as Malaysian or Manzanita wood, should be the primary focus of their diet.
• Supplements: Their diet should be supplemented with sinking pellets (including specialized xylivore formulas), algae wafers, and fresh vegetables like zucchini, cucumber, and blanched spinach.
• Feeding schedule: They prefer to graze throughout the day and are most active at night. 

• Temperament: L191 plecos are generally peaceful with other fish but can be territorial towards other bottom-dwellers, especially other plecos.
• Tank mates: Good tank mates include larger, peaceful, and active fish that occupy the middle and upper levels of the tank.
  • Compatible: Larger tetras (like Congo or Rummy-nose), angelfish, discus, and larger South American cichlids are all good options.
• Incompatible: They should not be kept with other territorial bottom-dwellers or with slow-moving fish that may be outcompeted for food.
