Zebra oto
Otocinclus cocama
Vertical blotches and a dark W-shaped tail mark distinguish this oto; mature grazing surfaces come first.
- Adult length
- Up to 4.4 cm (standard length, without the tail fin)
- Water temperature
- 21–25 °C
- pH
- 6–7.5
- Hardness

Keep a group in a mature, stable aquarium with plant and biofilm surfaces. Newly imported thin fish need close feeding checks.
Appearance and identification
Irregular dark bars stand on a pale body, with individual variation instead of a continuous lateral stripe.
Floor and movement space
Attributed base 45 × 30 cm; stage unspecified and group capacity unverified.
Aquarium environment
Leaves provide grazing and resting surfaces. Algae grazing does not remove the need for food or space.
Diet and feeding
Offer accepted plant-based sinking foods and monitor body condition.
Same-species behaviour
Group and feeding conditions require assessment; no verified stocking capacity.
