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

Well they could have the same problem, are you looking to set up a reef tank or a fish only tank? If it's a reef tank then you need to keep nutrients down as much as you can anyway and the extra light from the sun is actually beneficial. If it's a fish only tank with fancy filters and heavy bioloads then the nutrients may be higher and then algae will become a problem.
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.

Yes, but the frag tank has a backing to block out most of the sunlight. I tried an experiment to give the corals a bit more natural light, but it grew the bad algae faster so I now have a reflective white backing to block out sunlight.

The tank is going to have a blue plastic background and tin foil on the back to block most of the sunlight. I am going to give it a try and if it does not work I can always move to a different area.

I have my 60gal FOWLR very a large window. it has no backing. in short, yes algae does become a problem with all the sunlight although temperature swings have not been a problem for me.

I would definitely have a heavy curtain on the window. that way, if you want to cut the lights for a few days to kill off algae, you can do it without sunlight mucking up your plans.
