i norice that some jardini barbel get smaller as they get bigger, whys that. i seen a 12" jar at my lfs and the barbel was so small i could bearly see it. but i seen some bigger one with nice long barbel, any ideas?
Too small of a tank will rid your arowana of its beautiful barbles. I find that Jardini's have a thicker barbel at the 2ft mark when compared to other aro's at the same size.
