Is that aro in a 12" 55 gallon tank?[/QUOT
He's in a 5ft tank x 2ft high x 1ft deep
Yeah, I have overstocked before myself but there is waaay too much going on in there man. You have to get more familiar with these fish and their needs. BTW the Jacks aren't usually any more aggressive than anything else in that tank.
Can the aro still turn around? You need to upgrade that dude to like a 24"+ width
That's good that you are getting another tank, but your gonna need a big one for those guys. Most of those fish are young. The arowana though will grow to two feet long so he needs a much larger tank than you will ever be willing to buy.
