Hey I have a question regarding the 75 I have at the foot of my bed. It has a fully mature Red Devil/Midas along with a few giant danios. I prefer to sleep with my window open year round. In the winter I only crack it about an inch but when the weather is dropping below freezing every night it has a significant effect on the temperature of the room. During the summer months this obviously had no effect on the tank but now that its getting cold I have noticed that when I wake up in the morning the temp has dropped to around 77.1-77.5 from where it usually is 78.5-79 and then climbs back up to normal through out the day. Can this be causing unforeseen problems that I am not noticing because it doesn't seem to have any effect at all?
