Because silver aros max around 36" as adults; and even at 30" that's barely any room to turn. You want a minimum of AT LEAST 8x3x2 to take into account the aro hitting 36" and being able to turn.Its 30" wide, could you tell me what size tank you would recommend for one? I see plenty of people with arowana that grow to 24" in 180s and 240s so why would a 30" wide tank be too small for any arowana?
ArowsWell the tank is ok for a grow out. It won't be a long lasting grow out tho. Aria grow fairly quick.

Ok, I understand that they can get to 36" but I thought they would be able to turn in 30" as they're flexible, do they get to 36" quickly? The reason I was questioning the first reply is that he said no arowana could live in a 7x2.5x2 tank, surely an arowana that only reaches 24" could live in a 30" wide tank?
