Buying Guide: Key Purchase Considerations
- Light requirements: Cardinal plants typically prefer medium to bright light. If your tank has low lighting, color intensity may be muted or delayed.
- Growth pace and space: Some species grow quickly and require regular pruning to prevent crowding in smaller tanks. Plan layout accordingly.
- CO2 and nutrients: CO2 is optional for many cardinal plants but can enhance color development and growth in higher-light setups.
- Water conditions: Most cardinals prefer stable freshwater with normal hardness. Extreme temperatures can stress live plants; avoid shipping during severe cold or heat.
- Temperament with tankmates: Live plants can offer shelter and reduce stress for small fish; ensure compatibility with your species and size.
- Aquarium size and layout: Medium and larger tanks accommodate midground and background plants more effectively, creating depth and color contrast.
