Make sure that your fish tanks are not exposed to cold drafts at night – close doors, use door stoppers and window drapes to assist.
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.
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 Animates team members.
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.
To keep your aquarium environment healthy, you will also need to understand the nitrogen cycle, which is sometimes referred to as "biological filtration." Click here to learn more about the nitrogen cycle.
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.
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.
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. Click here to shop our wide fish food range.
