Gold Spotted (L-136) Plecostomus

Gold Spotted Plecostomus (L-136)

The Gold Spotted Plecostomus (L-136) is a striking and highly sought-after freshwater pleco admired for its shimmering golden spots that beautifully contrast against its darker body. This species is part of the Hypancistrus group, a family of plecos known for their unique colorations, manageable size, and peaceful nature. With its eye-catching appearance and hardy temperament, the Gold Spotted Pleco is an excellent choice for aquarists looking to add a rare and ornamental bottom-dweller to their aquarium.

Originating from the Rio Negro Basin in Brazil, the L-136 thrives in warm, soft, and slightly acidic waters where it spends much of its time hiding among driftwood, rocks, and riverbeds. In the aquarium, it demonstrates the same behavior, using caves and shaded areas as safe retreats. Though naturally shy, it becomes more visible once it acclimates and will actively forage, especially during evening hours.

The Gold Spotted Plecostomus is relatively small compared to some of its pleco cousins, typically reaching around 4–5 inches in length when fully grown. This modest size makes it a perfect fit for medium-sized aquariums of 30 gallons or more, though larger setups will allow for optimal swimming space and tankmate compatibility.

When it comes to water parameters, the L-136 prefers temperatures between 77–86°F (25–30°C), a pH of 6.0–7.5, and clean, well-oxygenated water. A reliable filtration system is vital, as this species thrives in high-quality water conditions with steady currents that replicate its natural river habitat.

Feeding the Gold Spotted Pleco is simple and rewarding. While it may graze on algae and biofilm, it is not an exclusive algae eater. Its omnivorous diet should include sinking pellets, pleco wafers, bloodworms, brine shrimp, and occasional fresh vegetables such as cucumber or zucchini. A balanced diet enhances both health and coloration, ensuring the golden spots remain vibrant.

This species is peaceful and adapts well to community aquariums with other non-aggressive fish of similar size. However, like many plecos, it can be territorial toward other bottom-dwellers, so providing multiple hiding places helps minimize stress and competition.

Breeding the L-136 in captivity is possible under the right conditions. As cave spawners, they require carefully placed caves or pleco breeding tubes. Males will guard the eggs until hatching, offering aquarists an exciting opportunity to raise their own generations of this rare fish.
