I want to put a small tank on one of my end tables-the size is 22" wide and 21" deep. I know that a regular 10 will fit, or a 15 hex (but those are so tall without much swimming room). I saw that there is an eclipse 12 that will fit but I'm not sure I want to mess with the easy-scratch of acrylic. Any glass tanks bigger than a 10, but wider than a 15 hex, that would fit on my table? If I have to I'll get the 10 but I'd like something a bit bigger.
