Review on Glass Hanging Creative Aquarium Garden by Nancy Knudsen

This aquarium is not suitable for any fish. It is so small that it is impossible to maintain the correct water chemistry (ammonia, nitrates, nitrites) that makes the water safe for fish. Bettas need at least 2.5 gallons to have enough water to dilute their waste without killing them from ammonia poisoning. Not to mention they need space for a filter and water heater! It would be nice if it was just a candle or decorative pill tray and not a live animal!
