Can otocinclus and angelfish live together?
Yes
Otocinclus and angelfish 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
| Otocinclus | Angelfish | Both | |
|---|---|---|---|
| Temperature | 72–79°F (22–26°C) | 76–84°F (24–29°C) | 76–79°F (24–26°C) |
| pH | 6.0–7.5 | 6.0–7.5 | 6.0–7.5 |
| Minimum tank | 10 gal (38 L) | 29 gal (110 L) | 29 gal (110 L) |
| Keep at least | 4 | 1 | |
| Adult size | 1.8 in (4.6 cm) | 6 in (15.2 cm) |
The smallest tank for both
A 29 gallons (110 L) tank holds 4 otocinclus and 1 angelfish at about 41% of its stocking limit, which leaves room for more.
