Betta Tank (Indoor) Specs, Water Temp, Water Quality and Fish Health

A brief overview of my AquaOne Betta Quad tank setup.

This system houses both male and female Halfmoon Bettas, allowing for observation of their distinct behaviours and colouration in a controlled environment. The females look similar.

Also, each compartment has a normal Bristlenose Plec (until it grows to big for the tank) to help with algae.

I’ve incorporated a Peace Lily as part of the nutrient‑management strategy. The plant’s roots help absorb excess nitrogen compounds, contributing to improved water quality. These began as small cuttings, and their growth demonstrates how effective emergent plants can be in supporting a low‑nutrient, stable aquarium ecosystem.

Water Temperature and Quality

• Maintain a tropical habitat at 24.5 to 27 degrees Celcius / 76-81 degrees Fahrenheit. Never below 62F or above 82F - Avoid drastic changes in water temperature and water quality.
• Betta fish prefer water in the pH range of 6.5-7.5.
• Ammonia should ideally be zero parts per million (ppm).
• Nitrate should be less than 40 parts per million (ppm).
• Nitrite should ideally be zero parts per million (ppm).
• Use water conditioner/dechlorinator to make tap water safe for bettas.
• Use an aquarium thermometer to monitor your tank’s temperature.
• Filter’s reduce ammonia, nitrate and nitrite levels, and preserve healthy bacteria.
• Use test strips to monitor water parameters.
