🐟 Golden Otocinclus (Otocinclus affinis)
Algae Control • Peaceful Community Fish • Nano Tank Cleaner
📋 The Golden Otocinclus is a unique color morph of the common Otocinclus, featuring a golden-yellow sheen across its body instead of the typical silver-grey. With its tiny size (4 – 5 cm), it is ideal for nano and planted aquariums.
This species is an exceptional algae grazer, feeding constantly on biofilm, diatoms, and soft green algae. Its peaceful schooling nature makes it a perfect addition to community setups, especially with shrimp, tetras, rasboras, and other small fish.
Though hardy once established, Golden Otocinclus are sensitive to poor water quality and require a mature, well-maintained aquarium with abundant algae and supplemental feeding.
