Can cardinal tetras and amano shrimp live together?
Yes
Cardinal tetras and amano shrimp can share a tank. Their water needs overlap and neither is known to bother the other.
Why
- Their temperature and pH ranges overlap comfortably, and neither is known to nip, chase or eat the other.
What each one needs
| Cardinal tetra | Amano shrimp | Both | |
|---|---|---|---|
| Temperature | 73–84°F (23–29°C) | 70–80°F (21–27°C) | 73–80°F (23–27°C) |
| pH | 5.0–7.0 | 6.5–7.5 | 6.5–7.0 |
| Minimum tank | 20 gal (76 L) | 10 gal (38 L) | 20 gal (76 L) |
| Keep at least | 6 | 3 | |
| Adult size | 2 in (5.1 cm) | 2 in (5.1 cm) |
The smallest tank for both
A 20 gallons (76 L) tank holds 6 cardinal tetras and 3 amano shrimp at about 35% of its stocking limit, which leaves room for more.
