Thai lion goldfish thrive at about 20-28°C, with 24°C ideal. Proper temperature keeps them active, speeds metabolism and growth, and strengthens health.
Above 30°C they feel unwell, may stop eating, and can become oxygen-starved. Keep the temperature stable, when changing water, keep the difference under 2°C to avoid shocking the fish.
