Hi all, I have a 6 inch jardini arowana, iv had him for 3 weeks. From day one he's always been straight to his food, never hid and was always patrolling his tank, yesterday he seemed a lot shyer, hiding in the plants a lot and when he did come out he was looking at his reflection on the glass, could this be that he thinks there's another arow in the tank and he's feeling aggressive? He also was more delicate when feeding.
When the lights are off he seems okay.
Thanks in advance

The Jar is young and still eating typical behavior imo. Just monitor your water parameters and do weekly wc's and good foods.
