Buying Guide
- Tank size and setup: Crowntail bettas typically do well in 5–10 gallon tanks with gentle filtration and stable temperatures around 76–82°F. Larger displays allow more elaborate fin displays and background blue hues.
- Color emphasis: If you want blue-blue aesthetics, prioritize fish with blue bodies or blue-tinished fins. White or orange accents can create high-contrast displays in blue-themed tanks.
- Care level: Betta fish are generally beginner-friendly but require regular water changes and compatible tank mates to prevent stress and fin-nipping. Avoid aggressive species that may chase or damage fins.
