    Can water be too warm?

    I am about to start a new aquarium. My first in Florida. Since the room temperature frequently is in the 80-83 degree range, will this be a problem? Is my choice of fish restricted? Is there a solution (if it's a problem)? Like 'water coolers' ??

  • Warmer water will usually make your fish more active. I have also heard that it 'speeds' up their life cycle. That temperature is not a problem for most tropicals. However,you may want to stay away from any coldwater fish or white clouds. My tanks are often 80-82 degrees in the summer if the air is off and this has never been a problem.

  • I agree with jd (hey, I hope it is okay to call you that, Joyce). As long as you stay away from the coldwater variety such as goldfish and white clouds, you should be fine. Before air conditioning in my home, my water would raise to sometimes 87 plus degrees. That is when the small plastic coke bottles filled with water and frozen would come in handy. When the water would become too warm, I would just plop one in, and all the fishies were refreshed. Just remember to try to keep whatever temperature the tank is constant. Severely fluctuating temperatures will stress the fish and cause disease.

  • Hey JD (i like the ring of that) and kick are right on the money (as always) the only thing I will trow in is that make sure your thermometer goes above 82F. alot of them dont and if you have a liquid metel thermometer then it could break and poision the fish. I have always used the stick on outside type and they are quite accurate. I always keep a glass one on hand.

  • JD is fine with me (new handle I guess).Good idea on the coke bottles Kick(fish airconditioning) and good one on the thermometer Steve. I also have a glass one, but rarely use it.The stick-ons are very convenient.

  • Depending on the "outside" environment, sometimes the sticky thermoms are not 100 percent accurate, but usually only vary a couple of degrees. These thermoms pick up the outside temp. somewhat and if by chance it is in the area of a furnace or air conditioning vent, it could vary from the inside of the tank. A very good thing to do to be sure the water inside the tank is appropriate is to "test" the outside thermom. Have an inside one on hand and place it in the tank periodically to see what the "actual" temp is inside. If it is the same or only varies slightly, it will work just fine. Most small glass aquarium thermoms (about $2 in most areas) have readings up to and over 104 degrees so I would hope these would not cause any problems. My bigger worry would be the heater.
