As the title says. I'm going to be buying a finnex LED and am unsure on the size iIshould get. I have a 15 gallon hex that is 15 inches across. The sizes come in 12 and 16 is bigger better or smaller?

Go with the 16 inch fixture, it will over hang a bit but will give you way better lighting than the 12 inch.
