Optimizing Tank Environment
Discus fish are sensitive and need a calm tank to reduce stress. Keeping their tank environment right helps them stay healthy.
Small changes in the tank setup can make a big difference. Focus on water, size, and decoration to keep discus happy.
Ideal Water Parameters
Discus need clean water with stable conditions. Keep the water soft and slightly acidic for best health.
