Betta fish can be reared together with water bamboo (Phyllostachys heteroclada), and this combination forms a beneficial symbiotic relationship. However, environmental control and daily maintenance require careful attention. The detailed analysis is as follows:
I. Symbiotic Advantages
Water Purification: As an aquatic plant, water bamboo effectively absorbs pollutants in water to help purify water quality. Betta fish produce waste such as feces during metabolism, which can become sources of water pollution. Water bamboo absorbs nutrients from this waste, reducing water contamination and providing a cleaner living environment for bettas .
Oxygen Supply: Water bamboo releases oxygen during its metabolic process, which helps increase dissolved oxygen levels in the water. Betta fish, belonging to the Anabantidae family, have unique labyrinth organs that allow them to absorb oxygen directly from the air. However, when water quality is poor or dissolved oxygen is insufficient, the oxygen released by water bamboo provides additional support for bettas .
Ecological Balance: The symbiosis between betta fish and water bamboo helps maintain ecological balance in the aquarium. Betta activity promotes water circulation, facilitating even distribution of water quality. Meanwhile, the growth of water bamboo provides shade and hiding spots, creating a more comfortable habitat for bettas .
II. Key Considerations
Water Level Control: Water bamboo roots can survive in water, but excessively high water levels may cause root rot. Therefore, when rearing bettas with water bamboo, the water level must be controlled to prevent the roots from being submerged for long periods. Materials like white quartz sand can be used to elevate the roots and avoid rot .
Lighting and Temperature: Both betta fish and water bamboo require suitable lighting and temperature conditions. Bettas thrive in well-lit environments with appropriate temperatures, while water bamboo prefers warm, humid conditions . It is essential to ensure both organisms receive optimal lighting and temperature when reared together.
Daily Maintenance: Regular tasks such as water changes, tank cleaning, and pruning yellowed leaves of water bamboo are indispensable. These practices help maintain clean water quality and healthy growth of water bamboo, thereby providing a better living environment for betta fish .
