Thanks RandomWiktor, It would be a Crown Tail. Would 14g be too big for 1 Crown Tail? Would 5g (18 x 9 x 9) with Java Moss be better for 1 male Betta? Also, since you have pointed out about Java Moss being too short, would a 18 x 9 x 9 be alright with Java Moss or would the 5 g also require taller plants?
