I am trying my hand at a 10 gallon planted tank this time around! My main question is on the water level.
Since the 10 gallon is of normal size (20l x 10w x 12h) and not a shorter height would it be better to keep the water level down a couple inches? If so how much?
I am just concerned that if I divide the tank and have two males they will struggle with swimming to the top. Anyone ever experience problems with this? Anyone have their bettas in say a 20gallon?
I know it may seem to be a silly question, but it is better to ask than be sorry!
