Common Otocinclus

Key differences: Often confused, but O. affinis (a common misnomer for O. vittatus in the trade) typically has a more continuous and less irregular lateral stripe.

Dwarf Otocinclus
Otocinclus macrospilus
Key differences: Similar in size and appearance, but O. macrospilus often has a more pronounced, often circular, dark spot at the caudal fin base, and its lateral stripe may be less defined or broken compared to O. vittatus.
Zebra Otocinclus
Otocinclus cocama
Key differences: Distinctly different with a striking black and white banded pattern, making it easily distinguishable from the more subdued coloration of O. vittatus.
