do my fish hate mondays?

[david05]

Hi, I own a biocube 14 that is in my office, we work from monday to friday. The average temperature outside the office is arround 86 degrees all year. During the weekends the air conditioner is OFF, the temperature rised the first time to 85. After that configured my apex to turn off the light if the TEMP goes over 81. this reduced the increase in temperature over the weekend to 82 degrees. Which take me to the topic of my thread, i do not see any sign of stress in my fish but wish to hear from fellow fishkeepers their opinion about the changes in temperatures in my case if they are considered to be stressfull or harmful for my fish.

attached temperature graph (weekly and from monday) from APEX.

Thank You

noticed that the temperature graph for monday is not clear, so here you can see the time lapse clearly

As temperatures rise, dissolved oxygen decreases. Best to keep temperature below 82 F or so.
