I keep my pairs in tanks between 5-10 gallons. Unless you were housing a large group of these fish, a 45 gallon certainly isn't necessary. They are a fairly sedentary fish, and seem to prefer to carve out small territories, rather than be constantly on the move.
You don't need to remove them from the tank when they spawn. Fish from this complex shouldn't eat their eggs or their fry. Any fish that does so in my fish room is either sold on or not used for spawning as it's not a trait I want carried onto future generations.
