Hello all. My arowana for the past day or two has been swimming quite low in my tank, and knowing that arowanas are top swimmers this strikes me as a little odd. he is eating fine and he does come up and swims around for a while, but he will from time to time sit at the bottom of the tank. should i be worried about this. By sight he looks totally healthy. No wounds or visible infection, what could be causing this. Also one of my GT has been hiding out alot which is not normal, the other GT died about a week ago after getting stuck in under a rock looking for a feeder, so i chock it up to stress. But maybe i have a larger problem brewing, Advice and comments welcome.
