I didnt know Rams would kill cories ):
I'm working on a 2 x 2 x 1 (30 Gallon) cory tank (yeah it is a weird tank, because its actually a modified terrarium =D). I'm planning on getting 5 different species of cories (peppered, panda, emerald green, false julii, pigmey, or more if I find any suitable one) and besides the cories, I wanted a fish that would be a nice edition who would stay near the surface rather than the ground. I was debating between an angel or two, and a ram. After hearing about the cory incident above, I think I'll go with the angels lol. Plus I dont think Rams would really stay between the mid-high water levels (like in your pic).
