| Temperature | 65°F to 72°F (18°C to 22°C) |
| pH | 7.0 to 7.5 |
| Ammonia | 0 ppm (parts per million) |
| Nitrites | 0 ppm |
| Nitrates | Less than 20 ppm |
Proper Filtration Systems
Good filtration removes waste and keeps water clear. Use filters that do not create strong currents. Gentle water flow protects tiny fry.
- Sponge filters for gentle biological filtration
- Hang-on-back filters with adjustable flow
- Internal filters with soft intake guards
