Tank Temperature Question

    Hello,

    So one of the ways I check my tank temps is with a digital thermometer. Sometimes throughout the day it will go from say 80.6 down to 80.2 and back up to like 80.9 and so on. I'm just curious if it's a big deal if the same degree fluctuates a little bit?

    I don't think that small of a change would stress out fish.

    Agreed...That's a very small difference in temp. I'd only get worried if you start fluctuating at least +/- 5 degrees in a short amount of time.

    And anyhow, digital thermometers arent perfect, they're going to go up and down a couple of 0.1 degrees (as long as everything else is stable) as the day progresses, fish swim by, etc

    Think about natural water ways have you ever dived into a river or creek on a hot summer day or the day before and after a large storm you find hot spots in side eddies or the top 2 feet are hot the rest is cold or the storm can bring the water temp up and down multiple degrees, in Nature water temp is pretty unstable you'll be fine

    I do weekly water changes but once a month I will intentionally fill the tank to be 1-2C (35F) cooler so as to stimulate spawning its natural
