Maintaining Aquarium Temperatures for Fish Health

Cichlid with ichMaintaining proper aquarium temperatures is essential for the health and well-being of your fish. While aquarium heaters do a pretty good job at this, the probability of fluctuations from fall through spring tends to be greater and possibly more detrimental. You may not even realize how much the temperature of the water changes through the day or day-to-day until you’re faced with ich or some other problem in your aquarium.

The Threat of Cool Temperatures

While our aquarium fish will rarely if ever be exposed to near or below freezing temperatures in the safety of your home (hopefully), fish farmers in Florida can attest to the immediate and lingering problems that can come with even short exposure to cold temps. Exposure to temps below 60 F can create chaos in a tropical tank, so you can imagine what freezing temps do to tropical fish housed in an outdoor setting. Sensitive fish may be killed outright from the shock of extreme temperatures or fluctuations in temperatures. Others face blows to their immune systems and the increased chance of being infected by opportunistic parasites, fungi or bacteria. These organisms take advantage at the slightest sign of stress on the part of tropical fish, and can decimate the population in a short amount of time. Cooler temperatures tend to make normally active fish lethargic and slower to react, making them more open to predation if outdoors. Similar problems can occur in the aquarium if smaller or more sensitive fish are not able to hide or escape the curiosity of larger, hardier tankmates.  Read More »

Tips For Keeping Your Aquarium Cool in Hot Weather

Ice CubesWhether you have a freshwater or saltwater aquarium, rising temperatures in the summer time can be a cause of concern. Aquariums shouldn’t be allowed to get hotter than 83°F, or dissolved oxygen levels in the water will start to diminish. This triggers a competition between fish and invertebrates for oxygen  leading to a very stressful situation, and possibly even death, for your aquarium inhabitants. Detailed below are some tips to help keep your aquarium cool when temperatures rise. Read More »
