Goldfish plants require bright, indirect light without direct sun exposure. They thrive in well-draining, slightly acidic to neutral soil with consistent moisture, avoiding overwatering. Warm temperatures around 65-75°F (18-24°C) and high humidity are ideal. Common challenges include aphids, mealybugs, and root rot. During spring and summer, goldfish plants may need more water and less during winter. In autumn, reduce feeding to prepare for dormancy.
