L519 Rio Itenez Pleco – Tank-Bred in Texas | Peaceful Bottom Cleaner, 1.25–2.0 in Juveniles
L519 Rio Itenez Plecos are a peaceful, hardy, and attractive dwarf Bristlenose-type pleco known for their honeycomb pattern, compact adult size, and useful grazing behavior. Their dark body, light spotting, and unique pattern make them a great choice for planted tanks, driftwood aquariums, pleco collections, and peaceful community setups.
These fish are tank-bred in Texas, making them a stronger and better-acclimated option compared with many imported plecos. They are small, peaceful bottom-dwelling catfish that spend much of their time grazing on biofilm, soft algae, driftwood, rocks, and aquarium surfaces while resting under caves, wood, or plants.
The fish currently available are juveniles around 1.25–2.0 inches. Adult L519 Rio Itenez Plecos typically reach about 3.5–4 inches when fully grown.

Adult Size: About 3.5–4 inches
Current Sale Size: Approximately 1.25–2.0 inches
Temperament: Peaceful
Care Level: Easy to moderate

Recommended Tank Setup
L519 Rio Itenez Plecos do best in a mature aquarium with clean, stable water, driftwood, caves, and shaded hiding areas. They are peaceful with most community fish, but like many plecos, adult males may become territorial toward other male plecos if there are not enough caves or hiding spots.
Minimum Tank Size: 20 gallons recommended for one adult
Group Size: Can be kept singly, as pairs, or in breeding groups with enough space and caves
Temperature: 72–82°F
pH: 6.0–7.8
Substrate: Sand or smooth gravel preferred
Tankmates: Peaceful community fish such as tetras, rasboras, guppies, endlers, corydoras, snails, shrimp, and other calm community fish
Driftwood is strongly recommended because L519 plecos naturally graze on wood, biofilm, and soft growth in the aquarium. Provide multiple caves, wood pieces, plants, or shaded areas so they feel secure.
Feeding
L519 Rio Itenez Plecos are good algae and biofilm grazers, but they should still be fed directly. They enjoy a varied diet of:
Algae wafers, sinking vegetable pellets, blanched zucchini, cucumber, green beans, spinach, Repashy, driftwood biofilm, occasional frozen bloodworms, and high-quality sinking foods.
They will graze on soft algae, biofilm, wood surfaces, and leftover food, but they still need regular feeding to stay healthy. A vegetable-based diet is important for good growth, body condition, and long-term health.

Important Notes
L519 Rio Itenez Plecos stay much smaller than common plecos, making them a better choice for most home aquariums. They are helpful algae and biofilm grazers, but they are not a replacement for regular tank maintenance. They still need clean water, proper food, driftwood, and hiding spaces.
Adult males may develop bristles and may guard caves once mature. Provide enough caves and hiding spaces if keeping more than one pleco.
