Goldfish tolerate lower temperatures. Kale and spinach are cold-tolerant greens that grow well in cooler climates.
Koi are ornamental and friendly fish. Herbs like mint and chives are easy to grow and suitable for balconies or small systems.
Catfish are robust and grow well in commercial tanks. Tomatoes and water spinach benefit from nutrient-rich water.
