Fish can become stressed during winter months, leading to health problems. Follow these seven simple tips to help your fish to continue to thrive when the temperature drops.

1. Avoid drafts

Make sure that your fish tanks are not exposed to cold drafts at night – close doors, use door stoppers and window drapes to assist.

2. Check temperature

It may sound obvious but take the time to check the temperature of your tank with a thermometer. Make sure the water temperature hasn’t dropped below ideal conditions for your fish.

3. Check the size of your heater

Use the manufacturer’s recommendations to check that your heater is big enough for your tank, or have a chat to one of our Petbarn team members.

4. Check water parameters

Eliminate any other stresses and ensure that your water quality is correct for the fish you keep. Purchase a quality testing kit and test your water regularly. To prevent issues, keep the tank clean and check that your filters are fully operational.

5. Avoid large water changes

Filling the tank with cold water can reduce the temperature significantly, leading to stress and disease. Try more frequent, but smaller, water changes instead.

6. Treat with medication as needed

Fish under temperature stress can commonly suffer from fungal disease or white spot. Keep an eye out for these, and treat with medication as needed.

7. Feed a nutritious diet

Boost the immune systems of your fish and ensure they are eating a quality diet. Frozen foods can also be a big help in adding vitamins and minerals to the diet.
