Is it a bad idea to put a saltwater fish tank right next to a window?

Heat would still be the biggest concern especially in a smaller tank

Thanks for your fast response!
It is going to be a reef tank with a couple of fish and invertebrates. I currently have a 29 gallon tank that's close to the window. I noticed that when I opened the blinds during the last few days that were sunny and the sun shone into the tank, the corals actually looked bigger and happier.

I am in the process of setting up a 20 gallon long and I would like to put it in my office infront of a window. I know that Anthony(Seahorsefanatic) has a reef tank infront of a window and the tank seems to be doing well.
