- Temperament: Semi-aggressive, particularly towards other male Bettas

Tank Requirements
- Tank Size: Minimum 5 gallons for a single Betta, but a 10-gallon tank or larger is ideal for more swimming space
- Water Temperature: 76°F to 82°F (24°C to 28°C)
- pH Range: 6.5 to 7.5
- Water Hardness: 5-15 dGH
- Substrate: Soft substrate such as fine gravel or sand; ensure there are no sharp objects that could damage their delicate fins
- Tank Setup: Bettas enjoy tanks with soft plants and hiding spaces. Live plants like Java Fern, Anubias, or Marimo Moss Balls are excellent choices. A gentle filter to maintain water quality without strong currents is ideal, as Bettas prefer calm waters. Floating plants can help mimic their natural environment and provide shelter.
Care Tips
- Water Quality: Bettas are relatively hardy but thrive in clean water with stable conditions. Perform regular water changes (20-30% weekly) to maintain water quality and prevent stress.
- Aggression: Male Koi Bettas are territorial and should not be kept with other male Bettas, as they will likely fight. If kept with other fish, ensure they are peaceful species. Females can be housed together in a sorority (4-5 or more), but this should be done with caution.
- Diet: Provide a varied diet, including Betta pellets, frozen or live foods. A balanced diet helps maintain their vibrant colors and overall health.
- Tankmates: When choosing tankmates, opt for peaceful species that will not provoke aggression. Suitable tankmates include small Tetras (e.g., Neon Tetras), Corydoras Catfish, or snails. Avoid fin-nipping species or other Betta males.

- Peaceful Tankmates: Suitable tankmates include peaceful fish like:
- Corydoras Catfish
- Neon Tetras
- Otocinclus
