* Ideal water temperature: 75-84°F (24-29°C)
* Minimum water temperature: 70°F (21°C)
* Heater required: Yes
Angelfish are tropical fish that need warm water to survive. They are most comfortable in water temperatures between 75-84°F (24-29°C). If the water temperature drops below 70°F (21°C), angelfish can become stressed and susceptible to disease. Therefore, a heater is required to maintain the water temperature within the ideal range for angelfish.
Neon tetras
* Ideal water temperature: 72-82°F (22-28°C)
* Minimum water temperature: 70°F (21°C)
* Heater required: Yes
Neon tetras are also tropical fish that need warm water to survive. They are most comfortable in water temperatures between 72-82°F (22-28°C). If the water temperature drops below 70°F (21°C), neon tetras can become stressed and susceptible to disease. Therefore, a heater is required to maintain the water temperature within the ideal range for neon tetras.
