So I picked this frag up a few weeks back at Kee's. And now I'm having a little trouble figuring out how to place it. Should I leave it on its side like in the Pictures or should I flip it so that the "mouth" is facing upwards towards the light ? I've tried it both ways, leaving it as is makes the sides puff up, and flipping it upwards makes the mouth puff up. So what do you think ?
