Overview
The opal spot pleco is a spotted Xingu pleco for a hot, fast-flowing tank. Its care is moderately demanding.
Did you know
The opal spot pleco was described in 2023 and named raonii for Cacique Raoni Metuktire. He is the Kayapo leader known worldwide for his campaign to protect the Xingu river and the wider Amazon rainforest.
Caring for the opal spot pleco
Give an opal spot pleco a warm tank of at least 79 gal (300 L). Stack smooth rock to form caves, and add some driftwood.
Hold the water hot and soft, at 81 to 88°F (27 to 31°C) and a pH of 6.0 to 7.2. Like the rapids it comes from, its tank should be turbulent and rich in oxygen, with brisk, strong flow.
It leans carnivorous rather than vegetarian. Build its diet around meaty sinking foods such as carnivore pellets, frozen bloodworm, mysis, prawn and mussel, with only some vegetable matter.
Keep it singly, since it is best kept as the only one of its kind. It is peaceful toward other species. It is an egg layer, and breeding it is of moderate difficulty.
