Can Zebra Otocinclus live with Cardinal Shrimp?
Caution — with care
Why
- Almost no shared temperature: Zebra Otocinclus wants 72–79°F and Cardinal Shrimp wants 79–84°F, so only 79°F suits both — too fine a margin to actually hold.
- Zebra Otocinclus will eat Cardinal Shrimp shrimplets. The colony still grows if there is moss or another dense hiding place for the babies.
- Only a narrow pH overlap — keep both around 7.5–7.5.
- Only a narrow water hardness overlap — keep both around 8–10 dGH.
Sweet spot: both do well at 79–79°F and pH 7.5–7.5 — aim there.
Side-by-side
| Zebra Otocinclus | Cardinal Shrimp | |
|---|---|---|
| Temperature | 72–79°F | 79–84°F |
| pH | 6–7.5 | 7.5–8.5 |
| Hardness (GH) | 2–10 dGH | 8–18 dGH |
| Adult size | 1.5" | 0.8" |

Together, plan on at least 15 gallons.
How to make it work
- Keep a large, established shrimp colony in a heavily planted tank with moss and cover so enough survive to breed.
- Target the overlapping water-parameter range and acclimate slowly.
Sort it with: An adjustable heater · GH remineraliser
