Penguin Fish's Lack of Swimming: Possible Causes Explai

The Reasons Why Parrotfish Don't Like to Swim and How to Solve Them

1. Low Water Temperature

Parrotfish tend to become less active primarily due to sudden changes in water temperature. Whether the temperature spikes or plummets, it can leave these tropical fish feeling listless and less inclined to swim. As tropical fish, they thrive in warmer waters, ideally maintaining temperatures above 25℃. It's crucial to prevent drastic fluctuations in water temperature, as sudden shifts can be quite stressful for them.

Solution: Maintain a Constant Water Temperature. To ensure your parrotfish remain active, avoid sudden temperature changes. Consider installing a heater in the aquarium to keep the water between 25℃ and 32℃, which is the ideal range for these fish. When changing water, be mindful of the temperature difference between the new and old water, aiming for no more than a 0.5℃ variance to minimize stress on the fish.

2. Poor Water Quality

Bad water conditions can also lead to a lack of activity in parrotfish. While it's not necessary to change the water too frequently, it's equally important not to neglect regular water changes. Depending on the filter's efficiency, you might need to change the water every two weeks or once a week. Adjust the frequency based on your aquarium's specific conditions. Neglecting water changes can lead to poor water quality, causing the fish to become inactive and potentially sick.

Solution: Install a filter in the aquarium to slow down water degradation and maintain good water quality. Regularly change the water to keep the environment healthy for your parrotfish.

3. Sudden Startle

Parrotfish can become extremely inactive and may even hide at the bottom of the tank if they're startled severely. They will try to minimize their presence to avoid detection.

Solution: Keep the environment quiet and avoid loud noises or shaking the tank. If your parrotfish appears startled, move the tank to a quieter, darker area to provide them with a sense of security and encourage them to return to normal activity.

4. Insufficient Oxygen Supply

Parrotfish have a higher oxygen demand compared to other fish. If the water lacks sufficient oxygen, they may struggle to breathe properly, leading to a decrease in activity as they conserve energy.

Solution: Regularly change the water to increase oxygen levels, and consider installing an air pump in the tank to oxygenate the water for 1 to 2 hours daily. Combining this with regular water changes will ensure the water remains welloxygenated.

In summary, to keep your parrotfish healthy and active, ensure the following conditions are met: maintain excellent water quality; keep the water temperature between 25℃ and 32℃; feed them a balanced diet with regular, measured portions; and regularly treat for parasites and bacteria, as well as promptly treating any sick fish.

That's all for today's tips. I hope your fish stay healthy and lively!
