Why you think my tank is dividedEach aro has full access to all areas of the tank.
PS- all my arowana are between 3 and 7 years old.
I've seen video of your tank; I know it's not divided. It is a nice setup (I especially like your loaches), but your aros seem to spend quite a bit of time avoiding bumping into one another. That to me is an indication that your tank is overstocked. Like I mentioned, it's all a matter of personal opinion. It's a subjective question, so there will be subjective responses.
PS- I like turtles.
