Water Parameters for Cichlids
Temperature, pH, and water chemistry requirements for different cichlid groups.
Water parameters influence fish health, digestion, and behavior. While exact numbers vary by species, stability is usually more important than chasing precise values.
Temperature
Most cichlids thrive between 75°F and 82°F (24–28°C). Sudden temperature swings can stress fish and increase disease risk.
pH and Hardness
Different groups evolved in different environments:
- African lake cichlids prefer harder, alkaline water.
- Many South American species prefer softer water.
Research the needs of the species you plan to keep.
Water Changes
Regular water changes are essential for removing waste and maintaining stable conditions.
Typical routine:
- weekly water change of 20–40%
- regular testing for ammonia and nitrate
Practical Example
A heavily stocked African cichlid tank may require larger or more frequent water changes compared with a lightly stocked planted aquarium.
Water Stability Basics
Testing and consistency matter more than chasing a perfect number on day one. For most beginner tanks, the useful basics are a dependable master test kit, a hardness test when species require it, and equipment that keeps temperature stable.
